Skip onMovementBoundsChanged when waiting for fixed rotation

When entering PiP from landscape mode with non-default aspect ratio, the
onMovementBoundsChanged callback will try to reset the surface with the
default bounds. Skip it if we are waiting for fixed rotation to be
completed, similar to the exiting swipe-pip-to-home check.
