Apply PictureInPictureSurfaceTransaction upon reparent

When autoEnterPip from Task with multiple activities, besides passing
the mLastRecentsAnimationBounds we should also try to pass the last
PictureInPictureSurfaceTransaction to the new Task and apply both.

Changed also
- deprecate the last recents animation bounds and use the transaction only
- reset the transform once applied to the original task

Known issue: original task appears transparent in overview once.
