We only send onAnimationEnd() if both object animator and spring animator have
ended. However, we also initialized mSpringEnded = false to begin with, which
meant we would never send onAnimationEnd() if the spring animator was never
started. Now we treat the animators as ended until they are started.
Example test:
0: Enable SWIPE_HOME and QUICKSTEP_SPRINGS flags
1: Swipe up and hold on home to go to overview
2: Tap outside overview to go home
3. Swipe up to all apps
4. Swipe down
Expected: animates to home, not overview. Before this change, however, it went
to overview because the state manager never got onAnimationEnd() and therefore
never set the last stable state to NORMAL instead of OVERVIEW.

* Listeners weren't getting called properly. We add one listener to the
SpringbjectAnimator and then use that to dispatch to the other listeners.
* We fast finish on both double swipe cases to prevent the shelf from
ending in an invalid state. This causes a visual jump but this can be
addressed in follow up CL.

Added new SpringObjectAnimator class that wraps an ObjectAnimator so the
Object can be controlled via the Animator or via a SpringAnimation. It extends
ValueAnimator so that it remains compatible with AnimatorPlaybackController.
Code is behind feature flag toggle QUICKSTEP_SPRINGS.
