Using it, a Flutter app can monitor missing frames in the release mode, and a custom Flutter runner (e.g., Fuchsia) can add a custom FrameRasterizedCallback. Related issues: https://github.com/flutter/flutter/issues/26154 https://github.com/flutter/flutter/issues/31444 https://github.com/flutter/flutter/issues/32447 Need review as soon as possible so we can merge this before the end of May to catch the milestone. Tests added: * NoNeedToReportTimingsByDefault * NeedsReportTimingsIsSetWithCallback * ReportTimingsIsCalled * FrameRasterizedCallbackIsCalled * FrameTimingSetsAndGetsProperly * onReportTimings preserves callback zone * FrameTiming.toString has the correct format This will need a manual engine roll as the TestWindow defined in the framework needs to implement onReportTimings.
