xwayland: Split up xwl_screen_post_damage into two phases

Browse Source 
The first phase sets the new surface properties for all damaged
windows, then the second phase commits all surface updates.

This is preparatory for the next change, there should be no observable
change in behaviour (other than the order of Wayland protocol
requests).
