Adding TaskViewSimulator for simulating taskView layout on a remote target

1. Tanslating contents of RecentsView instead of recentsView itself. When
   translating, we keep the current TaskView from moving. This allows
   the remoteTarget to follow an individual taskView.
2. Removing translationY in recentsView and setting the pivot instead
3. Using TaskViewSimulator for swipe handler. This allows using similar
   animation creation as Launcher window animation.
