[gui] Add {add,remove}RegionSamplingListener
Adds addRegionSamplingListener and removeRegionSamplingListener to
ISurfaceComposer. This interface will allow a client to register to
receive an updated median luma value for a region bounded by a stop
layer (i.e., layers behind the stop layer) and the provided Rect any
time the display updates.
Multiple areas may be sampled, but they must use separate listeners, and
the layer traversal will stop at the stop layer with the lesser Z value.
