Implement destroying surfaces

Browse source 
Add a signal for wlr_surface destruction on the wlr_surface that compositors
can listen to to remove the surface from their state.

Implement a listener for this in the example wl_compositor to remove the
surface from its internal list of surfaces.

Destroy the surface in the compositor destroy_surface callback given when the
surface resource was created.

Add a reference to the surface resource to the wlr_surface so a compositor can
find it in its list of resources upon wlr_resource destruction.
