Fixed transition animation from pipable activities
- Defer telling the client it is hidden if it can enter Pip and isn't
current stopped or stopping. This gives it a chance to enter Pip in
onPause().
- Once pause is complete set the visiblity to false to stop deferring
hiding client.
- Don't allow FLAG_RESUME_WHILE_PAUSING activity to resume until the
currently resumed activity is puased if the currently resumed activity
can enter Pip.
- Detach child surfaces added by the client process in
WindowState.sendAppVisibilityToClients() right before we notify the
client.
