core/compositor: make wl_surface::frame follow pending states (#11896)

* compositor: make pending states store frame callbacks

move frame callbacks to pending states so they are only committed in the
order they came depending on the buffer wait for readyness.

* buffer: damage is relative to current commit

ensure the damage is only used once, or we are constantly redrawing
things on state commits that isnt a buffer.

thanks PlasmaPower.

* compositor: move callbacks back to compositor

move SSurfaceStateFrameCB back to compositor in the class
CWLCallbackResource as per request, but still keep the state as owning.

* compositor: ensure commits come in order

if a buffer is waiting any commits after it might be non buffer commits
from the "future" and applying directly. and when the old buffer that
was waiting becomes ready it applies its states and overwrites the
future changes.

move things to scheduleState and add a m_pendingWaiting guard. and
schedule the next pending state from the old buffer commit when done.
and as such it loops itself and keeps thing orderly.
