SurfaceFlinger: Send all BufferedLayers to InputFlinger

Currently if an InputWindow is obscured by a window with
FLAG_NO_INPUT_CHANNEL or a Surface with no window (and input) at all
then InputDispatcher will not be aware of the window and it will
fail to generate FLAG_(PARTIALLY)_OCLUDED for windows underneath. To fix
this we make sure we generate an InputWindow for every buffered
element on the screen and make them all known to InputDispatcher.
