Fixes https://github.com/flutter/flutter/issues/130277
This PR does two things:
1. introduce a hidden `flutter build _preview` command, that will build a debug windows desktop app and copy it into the SDK's binary cache. This command is only intended to be run during packaging.
2. introduce a new device type, called `PreviewDevice`, which relies on the prebuilt desktop debug app from step 1, copies it into the target app's assets build folder, and then hot reloads their dart code into it.
Support for FFI calls with `@Native external` functions through Native assets on Windows. This enables bundling native code without any build-system boilerplate code.

### Implementation details for Windows.
Mainly follows the design of https://github.com/flutter/flutter/pull/134031.
Specifically for Windows in this PR is the logic for finding the compiler `cl.exe` and environment variables that contain the paths to the Windows headers `vcvars.bat` based on `vswhere.exe`.
Partial work towards 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.
## Background
The Windows runner has a race at startup:
1. **Platform thread**: creates a hidden window
2. **Platform thread**: launches the Flutter engine
3. **UI/Raster threads**: renders the first frame
4. **Platform thread**: Registers a callback to show the window once the next frame has been rendered.
Steps 3 and 4 happen in parallel and it is possible for step 3 to complete before step 4 starts. In this scenario, the next frame callback is never called and the window is never shown.
As a result the `windows_startup_test`'s test, which [verifies that the "show window" callback is called](1f09a8662d/dev/integration_tests/windows_startup_test/windows/runner/flutter_window.cpp (L60-L64)), can flake if the first frame is rendered before the show window callback has been registered.
## Solution
This change makes the runner schedule a frame after it registers the next frame callback. If step 3 hasn't completed yet, this no-ops as a frame is already scheduled. If step 3 has already completed, a new frame will be rendered, which will call the next frame callback and show the window.

You can now specify a --local-web-sdk flag to point to a wasm_release folder. This will make it so that only artifacts that pertain to the web sdk are overridden to point to the wasm_release folder. Other artifacts (such as impellerc) will pull from the cache, or from the --local-engine path if that is specified.
This also uses precompiled platform kernel files for both ddc and dart2js
* Dart2JS build step looks for compiled platform binaries.
* Use new locations of platform binaries.
* Added --local-web-sdk command line flag.
* Need to use the matching frontend server when doing ddc stuff.
* Update packages/flutter_tools/lib/src/test/web_test_compiler.dart

The `flutter doctor` command uses `vswhere.exe` to verify the Visual Studio installation. This `vswhere.exe` is known to encode its output incorrectly. This is problematic as the `description` property is localized, and in certain languages this results in invalid JSON due to the incorrect encoding.
This change introduces a fallback to our `vswhere.exe` output parsing logic: if parsing JSON fails, remove the `description` property and retry parsing the JSON.
This fix was also tested on the outputs provided here: https://github.com/flutter/flutter/issues/106601#issuecomment-1170138123
Addresses https://github.com/flutter/flutter/issues/106601
Previously developers had to edit their `Runner.rc` file to update their executable's version information. Now, version information will automatically be set from `flutter build`'s arguments or the `pubspec.yaml` file for new projects.

Flutter uses `vswhere.exe` to find Visual Studio installations and determine if they satisfy Flutter's requirements. However, `vswhere.exe`'s JSON output is known to contain bad UTF-8. This change ignores bad UTF-8 as long as they affect JSON properties that are either unused, or, used only for display purposes by Flutter.
Fixes: https://github.com/flutter/flutter/issues/102451
`VisualStudio` calls `vswhere.exe` to find Visual Studio installations and determine if they satisfy Flutter's requirements. Previously, `VisualStudio` stored the JSON output from `vswhere.exe` as `Map`s, resulting in duplicated logic to read the JSON output (once to validate values, second to expose values). Also, `VisualStudio` stored two copies of the JSON output (the latest valid installation as well as the latest VS installation).
This change simplifies `VisualStudio` by introducing a new `VswhereDetails`. This type contains the logic to read `vswhere.exe`'s JSON output, and, understand whether an installation is usable by Flutter. In the future, this `VswhereDetails` type will be used to make Flutter doctor resilient to bad UTF-8 output from `vswhere.exe`.

When desktop support is not present in an existing project, certain
flutter tool commands raise an error that direct the user to
documentation on how to add desktop support to an existing Flutter
project. In a recent revamp of the webside, the URL was very slightly
changed (flutter.dev -> docs.flutter.dev).
This updates the error message to output the new URL.
