core: refactor and improve surface commit (#9805)

Browse source 
* make CHLBufferReference not a SP anymore

* copy over release and acquire points in CHLBufferReference

* use CHLBufferReference in screencopy and toplevel export

TODO: use CHLBufferReference in direct scanout properly
      the only problem is the scanout buffer release timing,
      specifically the onBackendRelease mechanism

* cleanup SSurfaceState and surface pending commit tracking

* move surface code from DRMSyncobj, and move acquire to SSurfaceState

* use queue for comitted pending surface states like proto says

"The content update is placed in a queue until it becomes active." - wl_surface::commit

* drop, not release, prev buffer if 2nd buffer wl_surface.attach is sent

"A wl_buffer that has been attached and then replaced by another attach instead of committed will not receive a release event, and is not used by the compositor." - wl_surface::attach
