Fix more instances of flicker in subsurfaces

Browse source 
* frame_clock.c (StartFrame): If the end frame timer is being
used to, return True and reset end_frame_called.
* subcompositor.c (SubcompositorLookupView): Fix coordinate
lookup inside subsurfaces.
* xdg_surface.c (NoteFrame): Rearrange frame callback logic.
