Send ScreenCaptureListener to native screen capture requests.

Browse Source 
Allow for asynchronous screenshot by sending a ScreenCaptureListener to
handle screenshot callbacks. All existing calls are still synchronous
since the SurfaceControl method will block the caller until the results
from SurfaceFlinger are ready.

Test: power + volume down
Test: adb shell screencap
