6/ Update recents animation classes to have their respective responsibilities

- RecentsAnimationTargets: manages information about the targets only
  RecentsAnimationCallbacks: manages callbacks from WM about the animation
  RecentsAnimationWrapper: manages calls into WM to update the animation
                           (to be renamed accordingly in a follow up CL)
- Create the Callbacks as a part of starting the recents animation, and
  have the callbacks create the controller wrapper and the targets, which
  are both notified to the listeners through the callbacks.
- Instead of passing through a callback for recents animation finished,
  have it be a part of the recents animation callbacks.
