wayland: Set the damage buffer size when supported

Browse source 
The preferred method for setting the damage region on compositor protocol versions 4 and above is to use wl_surface.damage_buffer. Use this when available and only fall back to wl_surface.damage on older versions.

Bumps the highest supported version of wl_compositor to version 4.
