Fix race of releasing leashes with shell recents transition
The code flow:
RecentsAnimationController#finishController
mOnFinishedListener.accept(this);
RecentsAnimationCallbacks#onAnimationFinished
*Post to "main" thread
RecentsAnimationListener#onRecentsAnimationFinished
TaskAnimationManager#cleanUpRecentsAnimation
Invoke SurfaceControl#release
*Post to "UiThreadHelper" thread
RemoteTransitionCompat.RecentsControllerWrap#finish
Invoke SurfaceControl.Transaction#remove
on the same SurfaceControl.
Then it may be either NullPointerException from
SurfaceControl#checkNotReleased. Or rarely native crash by
changing the surface control from 2 threads at the same time.
