Ensure --no-track-widget-creation is piped through android/macOS. Adds integration testing for iOS/android/macOS

Introduce BuildSystem.buildIncremental, which keeps an in-memory cache of timestamps instead of file hashes. This will be used to implement localization generation through the same build system API.

Ensure iOS and android builds can be correctly cached. Use the performance-measurement-file to verify that all targets were skipped on the second invocation. This is only run on the flutter_gallery build.

Avoid syncing unchanged versions of these files during hot restart/reload. This happens if the asset bundle needs to be built but produces identical manifests/licenses due to only asset contents changing

Support bundling SkSL shaders into an android APK or appbundle via the --bundle-sksl-path command line options. If provided, these are validated for platform engine revision and then placed in flutter_assets/io.flutter.shaders.json

The resident runner does not check if the ApplicationPackage is null when trying to stop the app. Update AndroidDevice.stopApp to handle this case by returning false.

The package will be null when flutter attach is used.

Finishes the gradual vm service migration by deleting the flutter tooling's vm_service

Fixes the performance issue with tree-shake-icons and filters to ttf mime type. Does not change default or error behavior.

Constructing the WebDevices with the global logger too early will lead to them grabbing the StdoutLogger when running in daemon mode. This prevents IDEs from seeing the correct debug message.

Move FlutterView and related RPCs to the package:vm_service implementation. Update some getIsolate calls with catchError to match previous behavior.

- Updates tests that were previously mocking FlutterViews to use real views
- Moves the FlutterView cache from VM to FlutterDevice
- Catch SentinelException during Isolate.kill

This reverts commit a18e6361.

Support --enable-experiment in flutter test (for flutter_tester). Required minor change for null safety.

This reverts commit 2e50fd75.

- Update the Linux build to support most of the build configuration, though like windows most only make sense for profile/release.
- Ensure VERBOSE_SCRIPT_LOGGING is set when the logger is verbose
- Automatically run pub get like other build commands

- Update windows precache to include placeholder profile/release artifacts
- Update Linux and windows unpack to account for the cpp_client_wrapper code to live separate from the engine binaries
- Cleanup testing in unpack_linux and remove test cases that are covered in build_system_test.dart
