Add spring to shelf for home <-> overview <-> all apps state transitions.

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.
