This reverts commit 9ed3e5be.

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.

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.

* Revert "Revert "Send text error in JSON and print in tools (#58284)" (#58872)"

This reverts commit c2d5e18c.

* Put streamListen in try/catch if extension events already listened for

instead of restricting profile/release mode based on whether the tool thinks the device is an emulator, restrict based on the device target architecture and the requested build mode. Notably, this enables release mode on x86_64 Android emulators, but not x86 emulators since we do not support that as an AOT target.

This does not add release mode support for simulators, since this requires us to build and upload artifacts for simulator/x86_64

Instead of targets/dart.dart -> targets/common.dart

Turn off flaky indicator for flutter_gallery__back_button_memory and flutter_gallery__memory_nav (#58838)

After updating the GBoard on the devicelab machines, these tests are no longer flaky.
