Fixes #53115

flutter analyze was unconditionally using the cached dart-sdk for analysis, and was not running with the built SDK during local engine. This broke when trying to update the analyzer for null safety, since it required us to wait for the dart change to roll into the framework first.

This reverts commit 9ed3e5be.

As of flutter.dev/go/engine-cpu-profiling, we collect the CPU and
Memory usage. With work being done to collect GPU usage on iOS as well.

This adds them to the timeline summary.

This reverts commit 43e28084.

This PR makes _RenderSlider not be a semantics container. This is so that the FocusableActionDetector in the Slider widget will get to aggregate the semantics information, since otherwise Talkback won't focus the slider because it thinks that the focus node doesn't have anything to say (which it doesn't but the _RenderSlider child does). If the _RenderSlider is a semantics container, then it keeps its speakable information to itself, but it isn't the Focus widget, so when the keyboard focus goes to the focus node, the accessibility focus doesn't move.

Since the _RenderSlider is always wrapped by the Slider widget, there's nothing lost in making it not be a container.

update flutter_service_worker.js to NOTICES
