Fixes autoEnterPip transition from landscape

Fixes included in this change
- PiP bounces back to fullscreen. The animation direction is not cleaned
  up after animation finishes and when display rotation callback
  happens and calls into PipTaskOrganizer#onMovementBoundsChanged, it
  accidentally invokes the onTaskVanished. Therefore, this does not
  happen on the first try but following attempts.
- PiP window offsets to the bottom caused by duplicated display changed
  callbacks, bail early if we know for sure the DisplayLayout objects
  are identical. Also, when display rotation callback happens, the
  PipBoundsState#getNormalBounds is still in landscape though the
  internal rotation has been set in PipController#startSwipePipToHome.

Known issue
- PiP window flickers at the end of the transition, will track in
  different bug.
