Xcode uses the CONFIGURATION_BUILD_DIR build setting to determine the location of the bundle to build and install. When launching an app via Xcode with the Xcode debug workflow (for iOS 17 physical devices), temporarily set the CONFIGURATION_BUILD_DIR to the location of the bundle so Xcode can find it.
Also, added a Xcode Debug version of the `microbenchmarks_ios` integration test since it uses `flutter run --profile` without using `--use-application-binary`.

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.
* dev/devicelab/bin/tasks/native_assets_ios.dart
* Runs an example app with native assets in all build modes, doing hot reload and hot restart in debug mode.
* dev/devicelab/bin/tasks/native_assets_ios_simulator.dart
* Runs an example app with native assets, doing hot reload and hot restart.
* packages/flutter_tools/test/integration.shard/native_assets_test.dart
* Runs (incl hot reload/hot restart), builds, builds frameworks for iOS, MacOS and flutter-tester.
* packages/flutter_tools/test/general.shard/build_system/targets/native_assets_test.dart
* Unit tests the new Target in the backend.
* packages/flutter_tools/test/general.shard/ios/native_assets_test.dart
* packages/flutter_tools/test/general.shard/macos/native_assets_test.dart
* Unit tests the native assets being packaged on a iOS/MacOS build.
It also extends various existing tests:
* dev/devicelab/bin/tasks/module_test_ios.dart
* Exercises the add2app scenario.
* packages/flutter_tools/test/general.shard/features_test.dart
* Unit test the new feature flag.
Sometimes `ios-deploy` loses connection to the device after installing, starting debugserver, and launching. This is shown with an error message like:
```
Process 579 exited with status = -1 (0xffffffff) lost connection
```
This happens frequently in our CI system: https://github.com/flutter/flutter/issues/120808
Usually in CI, on retry it'll work and pass - so this is an attempt to retry without failing the test first. It's not guaranteed to fix since we're unable to recreate this error locally.
â¦on file
The deeplink validation tool will become an static app so it can't no longer access vm services.
The goal will be then to turn them into flutter analyze command similar to `flutter analyze --android --[options]` that static app can use on.
This pr only removes vm services and turn the api to dump a output file instead of printing everything to stdout.
The `.packages` file was deprecated in Dart 2.8 and slowly discontinued until support being fully removed in Dart 2.19. The file will no longer be created, so it can be safely dropped from the generated `.gitignore` files.
Since applink validation tool is going to be a static tool, It won't have access to vmservices.
[flutter.dev/go/static-tooling-in-devtools](http://flutter.dev/go/static-tooling-in-devtools)
I remove the vm services and also update the deeplink task to also include path pattern and custom scheme

Fixes https://github.com/flutter/flutter/issues/133093
When I introduced the new, more robust version file `//flutter/bin/cache/version.json` in https://github.com/flutter/flutter/pull/124558, I changed `class FlutterVersion` into an abstract interface, implemented by `_FlutterVersionFromGit` (which is essentially the previous behavior) and `_FlutterVersionFromFile`, which merely reads the data it would have computed via git from `//flutter/bin/cache/version.json`.
While doing this, I made `_FlutterVersionFromGit.ensureVersionFile()` to be a no-op, since I assumed this would not be necessary since we already had a version file in the cache. However, this method was what was previously responsible for ensuring `//flutter/version` existed on disk. This means that if, for whatever reason, the user had `//flutter/bin/cache/flutter.version.json` present but NOT `//flutter/version`, the tool would have never created that file, and they would hit the tool crash seen in https://github.com/flutter/flutter/issues/133093.
This fixes the tool by ensuring `//flutter/version` exists regardless of if we're hydrating `FlutterVersion` from `//flutter/bin/cache/flutter.version.json` or not.
This makes two changes to prepare for incoming changes to skwasm in the web engine:
* We will (at least for now) be depending on the `WebAssembly.Function` constructor in `skwasm`, which is hidden behind the `--experimental-wasm-type-reflection` flag. We need to pass that when running skwasm benchmarks.
* We are going to be upgrading the skwasm build to a newer version of emscripten, which exposes the wasm exports via the `wasmExports` property instead of the `asm` property. Make sure to support either, if passed.
1. Remove vm service registration
2. combine print<variant>ApplicationId and print<variant>AppLinkDomain into one task dump<variant>AppLinkSettings, which dump all the data in a json file
The deeplink validation tool will be a static app in devtool instead of regular app. A Static app doesn't require a running app; therefore, we can't call these API through vmservices. I decided to convert these API into flutter analyzer command, which will be done in a separate PR https://github.com/flutter/flutter/pull/131009.
The reason these print tasks are converted into file dumps is to reduce the amount of data encoding and decoding. Instead of passing data through stdout, the devtool can read the files generated by gradle tasks instead.

Starting in Xcode 15, when building macOS, DT_TOOLCHAIN_DIR cannot be used to evaluate LD_RUNPATH_SEARCH_PATHS or LIBRARY_SEARCH_PATHS. `xcodebuild` error message recommend using TOOLCHAIN_DIR instead.
Since Xcode 15 isn't in CI, I tested it in a one-off `led` test:
* [Pre-fix failure](04e485a0b1/+/build.proto)
* [Post-fix success](d454a3e181/+/build.proto)
Fixes https://github.com/flutter/flutter/issues/132755.
Currently, flutter pub get generates localizations if there exists an l10n.yaml file where synthetic-package is not false. However, for any user who needs to turn off synthetic-package, their localizations are not generated. This PR should make the behavior more consistent. (Also it seems good to make it so that running flutter pub get once resolves all the dependencies so that people can get to work without running flutter gen-l10n manually.)

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. The implementation is based on a [short discussion with @christopherfujino](https://discord.com/channels/608014603317936148/608022056616853515/1141503921546875110):

> Not sure whether to post here or â hackers-infra-ð¡ , but is there a way to (and is it advisable to) detect whether the tool is running in a CI environment? I'd like to "soft enforce" --local-engine-host being provided strictly on CI, make sure that lands well, and then "upgrade" it to being non-CI invocations as well (re: https://github.com/flutter/flutter/issues/132245).

I also couldn't help myself to do a very minor refactor and add some comments to `LocalEngineInfo` because I was getting confused myself implementing it.
PR #132346 added the use of --local-engine-host to flutter_tools internals, and had an error on one line. Fix that error, to use the correct field name.
The error occurs when building plugins with the changed tools.

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.
At some point in the near future, we'll start an Impeller on Android preivew - and later make it the default. Unlike Skia, Impeller does not have a fallback software rendering mode. We'd like to stop suggesting this as an option now, and in the future remove the option to force software rendering.
Once impeller is the default, asking for software rendering on Android will result in either an error or falling back to Skia.
Fixes a couple of issues introduced in new iOS 17 physical device tooling: https://github.com/flutter/flutter/pull/131865.
1) Duplicate messages were being filtered out too aggressively.
For example, if on the counter app, you printed "Increment!" on button click, it would only print once no matter how many times you clicked.
Sometimes more than one log source is used at a time and the original intention was to filter duplicates between two log sources, so it wouldn't print the same message from both logs. However, it would also filter when the same message was added more than once via the same log.
The new solution distinguishes a "primary" and a "fallback" log source and prefers to use the primary source unless it's not working, in which it'll use the fallback. If the fallback is faster than the primary, the primary will exclude the logs received by the fallback in a 1-to-1 fashion to prevent too-aggressive filtering. Once a flutter-message has been received by the primary source, fallback messages will be ignored.
Note: iOS < 17 did not regress.
2) There was a race condition between the shutdown hooks and exiting XcodeDebug that was causing a crash when deleting a file that doesn't exist. This only affects CI - for the new integration tests and when testing with iOS 17 physical devices.
