Add deferTransaction variant taking GraphicBufferProducer.

For SurfaceView using child layers, the client framework
will not have access to the Handle* for the parent surface,
but still needs a way to defer transactions to it's frames.

Test: Tested with corresponding SurfaceView modifications and existing tests.
