* Run encode kn character encoding tool when gen_localizations is run

* Add test that ensures *_kn.arb files are properly encoded/escaped in order to be checked in

* Fix *_no.arb test to not incorrectly pass

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.

This adds an ExcludeFocus widget that prevents widgets in a subtree from having or obtaining focus. It also adds the ability for a FocusNode to conditionally prevent its children from being focusable when it isn't focusable (i.e. when canRequestFocus is false).

It does this by adding an descendantsAreFocusable attribute to the FocusNode, which, when false, prevents the descendants of the node from being focusable (and removes focus from them if they are currently focused).

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

Change display mode of PWA default to standalone, update integration test manifest to new default

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.

Fixed #55858

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.
