wayland: Updates the wayland compositor side support

Browse Source 
The compositor side wayland support enabling us to create textures from
wayland buffers needed updating since visuals were removed from the
wayland protocol.

This also fixes the #ifdef guards for the bind_wayland_display extension
in cogl-winsys-egl-feature-functions.h since it was mistakenly checking
that client-side wayland support had been enabled which won't be the
case.
