Add synchronous transaction to wait for setInputWindow to complete (1/n)
Add SurfaceFlinger callback to notify when input windows have been set.
The call to set input windows from SF to InputDispatcher is one way.
Therefore, it won't wait to ensure the windows have been set. Add a
callback method to allow InputDispatcher to notify SF when it's finished
setting the input windows, allowing SF to block if needed.
