Resolves#81831.
The PR improves the `config` command in below ways:
- Does not print the settings in usages or other options.
- Adds the `--list` flag to print the full settings list.
- Separates usages for settings and analytics.
- Prints the restart tip when clearing features.
Removes an ignore about overriding fields. Instead we just assign the value to the original field in the super class.
Related to https://github.com/dart-lang/language/issues/3332 (discovered during investigations into the violation of that lint).
This analytics event only records the value of the plist entry on
`build` commands. This will give an idea of the proportion of users who
are disabling Impeller when shipping apps.
Adds warning to `flutter create` command that checks if detected Java version is compatible with the template AGP and template Gradle versions. If a developer is building for Android and their Java version is incompatible with either the AGP or Gradle versions that Flutter currently supports by default for new Flutter projects, then
- a warning will show noting the incompatibility and
- steps will be shown to fix the issue, the recommended option being to configure a new compatible Java version given that Flutter knows we can support the template Gradle/AGP versions and updating them manually may be risky (feedback on this approach would be greatly appreciated!)
Given that the template AGP and Gradle versions are compatible, this PR assumes that the detected Java version may only conflict with one of the template AGP or Gradle versions because:
- the minimum Java version for a given AGP version is less than the maximum Java version compatible for the minimum Gradle version required for that AGP version (too low a Java version will fail AGP compatibility test, but not Gradle compatibility).
- the maximum Java version compatible with minimum Gradle version for a given AGP version is higher than minimum Java version required for that AGP version (too high a Java version will fail Gradle compatibility test, but not AGP compatibility test).
Fixes https://github.com/flutter/flutter/issues/130515 in the sense that `flutter create foo`; `cd foo`; `flutter run` should always be successful.

Per the dart2js team on the linked issue, `-O0` is not intended for end users, but more for actual debugging/development of the compiler.
Support for FFI calls with `@Native external` functions through Native assets on MacOS and iOS. This enables bundling native code without any build-system boilerplate code.

### Implementation details for MacOS and iOS.
Dylibs are bundled by (1) making them fat binaries if multiple architectures are targeted, (2) code signing these, and (3) copying them to the frameworks folder. These steps are done manual rather than via CocoaPods. CocoaPods would have done the same steps, but (a) needs the dylibs to be there before the `xcodebuild` invocation (we could trick it, by having a minimal dylib in the place and replace it during the build process, that works), and (b) can't deal with having no dylibs to be bundled (we'd have to bundle a dummy dylib or include some dummy C code in the build file).
The dylibs are build as a new target inside flutter assemble, as that is the moment we know what build-mode and architecture to target.
The mapping from asset id to dylib-path is passed in to every kernel compilation path. The interesting case is hot-restart where the initial kernel file is compiled by the "inner" flutter assemble, while after hot restart the "outer" flutter run compiled kernel file is pushed to the device. Both kernel files need to contain the mapping. The "inner" flutter assemble gets its mapping from the NativeAssets target which builds the native assets. The "outer" flutter run get its mapping from a dry-run invocation. Since this hot restart can be used for multiple target devices (`flutter run -d all`) it contains the mapping for all known targets.
### Example vs template
The PR includes a new template that uses the new native assets in a package and has an app importing that. Separate discussion in: https://github.com/flutter/flutter/issues/131209.
### Tests
This PR adds new tests to cover the various use cases.

The goal here is to "sniff" out any missing pieces that would block engine builds, rolls, benchmarks and so on before requiring humans to provide the parameter.

I made a minor refactor to test-only code because it was too confusing
to have 2 optional parameters that are technically required together,
but otherwise all other changes *should* be pass throughs. That being
said, I can't say I totally understand the Gradle stuff so I could use a
hand double checking that.

Part of https://github.com/flutter/flutter/issues/47161
Before this change, there were two places we overrode the `Artifacts` in a Zone:
1. if/when we parse local-engine CLI options: 1cf3907407/packages/flutter_tools/lib/src/runner/flutter_command_runner.dart (L281)
2. an additional override for fuchsia platform dill (no longer used, deleted in this PR): 1cf3907407/packages/flutter_tools/lib/src/commands/attach.dart (L274)
Note 1 above creates a new instance of `Artifacts.getLocalEngine()`. In this flow, there exist two instances of `Artifacts`:
1. The default fallback instance of `CachedArtifacts` (which gets all artifacts from flutter/bin/cache), instantiated in context_runner.dart: 1cf3907407/packages/flutter_tools/lib/src/context_runner.dart (L137)
2. An instance of `CachedLocalEngineArtifacts` created in the command runner once the CLI options have been parsed: 1cf3907407/packages/flutter_tools/lib/src/runner/flutter_command_runner.dart (L281)
The regression happened when we direct injected the Artifacts 1 from above BEFORE we parsed the local-engine flag, and then used this in the second zone override, and then when creating the `FlutterDevice` there are multiple calls to `globals.artifacts` returned it when it should have returned Artifacts 2: 1cf3907407/packages/flutter_tools/lib/src/resident_runner.dart (L80)
Device.artifactOverrides was originally introduced in https://github.com/flutter/flutter/pull/32071, but is no longer used, so I deleted it.
I also removed direct injection of `Artifacts` to the attach sub-command, because that class now no longer references artifacts.
I believe the ideal true fix for this would be to:
1. Migrate all leaf calls to `globals.artifacts` to use direct injection (in this case, the offending invocations were in [`FlutterDevice.create()`](1cf3907407/packages/flutter_tools/lib/src/resident_runner.dart (L80-L218)), but I'm not sure that something else would not have broken later)
2. Ensure we are always direct injecting the desired instance of `Artifacts`--that is, if the user desires local engine artifacts, that we are passing an instance of `CachedLocalEngineArtifacts`.
a. Alternatively, and probably simpler, teach `CachedArtifacts` to know about the local engine. This would mean parsing the global CLI options BEFORE we ever construct any instance of `Artifacts`.
As an overall recommendation for implementing https://github.com/flutter/flutter/issues/47161, in the overall tree of tool function calls, we should probably migrate the leaves first (that is, migrate the sub-commands last). We should also audit and reconsider any usage of `runZoned()` or `context.run()` for the purpose overriding zoneValues.
The display name will fallback to CFBundleName if CFBundleDisplayName is absent.

PR provides a new option to the `test` command to include coverage info of specified packages.
It helps collecting coverage info in test setups where test code lives in separate packages or for multi-package projects.
At present, only current package is included to the final report.
Usage:
Consider an app with two packages: `app`, `common`.
Some of the tests in `app` use (indirectly) code that is located in `common`. When running with `--coverage` flag, that code is not included in the coverage report by default. To include `common` package in report, we can run:
```sh
flutter test --coverage --coverage-package app --coverage-package common
```
Note that `--coverage-package` accepts regular expression.

Most of the actual changes here are in [packages/flutter_tools/lib/src/version.dart](https://github.com/flutter/flutter/pull/124558/files#diff-092e00109d9e1589fbc7c6de750e29a6ae512b2dd44e85d60028953561201605), while the rest is largely just addressing changes to the constructor of `FlutterVersion` which now has different dependencies.
This change makes `FlutterVersion` an interface with two concrete implementations:
1. `_FlutterVersionGit` which is mostly the previous implementation, and
2. `_FlutterVersionFromFile` which will read a new `.version.json` file from the root of the repo
The [`FlutterVersion` constructor](https://github.com/flutter/flutter/pull/124558/files#diff-092e00109d9e1589fbc7c6de750e29a6ae512b2dd44e85d60028953561201605R70) is now a factory that first checks if `.version.json` exists, and if so returns an instance of `_FlutterVersionFromGit` else it returns the fallback `_FlutterVersionGit` which will end up writing `.version.json` so that we don't need to re-calculate the version on the next invocation.
`.version.json` will be deleted in the bash/batch entrypoints any time we need to rebuild he tool (this will usually be because the user did `flutter upgrade` or `flutter channel`, or manually changed the commit with git).
Presubmit testing and CI testing of Flutter using a custom storage location for engine artifacts must be able to use the --fatal-warnings flag without failing due to the custom artifact location.
This change adds an option that makes this warning non-fatal. The new --no-fatal-storage-url-warning flag makes the --fatal-warnings flag ignore the warning that a custom artifact download URL is being used by setting the environment variable FLUTTER_STORAGE_BASE_URL.

## How we determine the channel name
Historically, we used the current branch's upstream to figure out the current channel name. I have no idea why. I traced it back to https://github.com/flutter/flutter/pull/446/files where @abarth implement this and I reviewed that PR and left no comment on it at the time.
I think this is confusing. You can be on a branch and it tells you that your channel is different. That seems weird.
This PR changes the logic to uses the current branch as the channel name.
## How we display channels
The main reason this PR exists is to add channel descriptions to the `flutter channel` list:
```
ianh@burmese:~/dev/flutter/packages/flutter_tools$ flutter channel
Flutter channels:
master (tip of tree, for contributors)
main (tip of tree, follows master channel)
beta (updated monthly, recommended for experienced users)
stable (updated quarterly, for new users and for production app releases)
* foo_bar
Currently not on an official channel.
ianh@burmese:~/dev/flutter/packages/flutter_tools$
```
## Other changes
I made a few other changes while I was at it:
* If you're not on an official channel, we used to imply `--show-all`, but now we don't, we just show the official channels plus yours. This avoids flooding the screen in the case the user is on a weird channel and just wants to know what channel they're on.
* I made the tool more consistent about how it handles unofficial branches. Now it's always `[user branch]`.
* I slightly adjusted how unknown versions are rendered so it's clearer the version is unknown rather than just having the word "Unknown" floating in the output without context.
* Simplified some of the code.
* Made some of the tests more strict (checking all output rather than just some aspects of it).
* Changed the MockFlutterVersion to implement the FlutterVersion API more strictly.
* I made sure we escape the output to `.metadata` to avoid potential injection bugs (previously we just inlined the version and channel name verbatim with no escaping, which is super sketchy).
* Tweaked the help text for the `downgrade` command to be clearer.
* Removed some misleading text in some error messages.
* Made the `.metadata` generator consistent with the template file.
* Removed some obsolete code to do with the `dev` branch.
## Reviewer notes
I'm worried that there are implications to some of these changes that I am not aware of, so please don't assume I know what I'm doing when reviewing this code. :-)
xcodebuild command generates a xcresult bundle file on each run, however, it doesn't delete the file generated from previous run and will throw an error if the exact file already exists.
In tool, we manually delete the file after each `flutter build` or `flutter run` command. However, there are some internal logic where xcodebuild retries multiple times.
This PR deletes the xcresult bundle file at the start of each retry if it exists.
