RemoteAnimations: Add failsafe

Adds failsafe mechanisms to RemoteAnimation and RecentsAnimation:
- cancel animations on binder death
- schedule a short timeout for RecentsAnimation after HOME and POWER events

Also enables RemoteAnimationControllerTest for presubmit, since it's turned
out to be reliable.

Change-Id: Id0bfdbee7d36f662eb386727195da8de2ed1684a
Fixes: 73496879
Test: kill / suspend launcher during animations; verify animations get aborted as expected.
Test: atest RemoteAnimationControllerTest
