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.
