wayland: Split MetaWaylandDataSource into a separate file
The split wasn't 100% clean, and some extra private API had to be added for it (but well, looking at the API, it's already evident there's a cleanup/streamlining task due). This is meant to be a refactor with no functional changes, so just go with it. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
