wayland-surface: Make _set_surface api public

Browse Source 
This exposes a clutter_wayland_surface_set_surface() function. The
implementation ignores requests to re-set the same surface and since now
has code to cleanup old surface state before setting the new surface.
(previously the surface was construct only so this wasn't necessary)
