wayland: Move MetaWaylandDataOffer to its own file
This is still an openly defined struct, as we will need accessed by "subclasses". Same principle applies than with the MetaWaylandDataSource refactor, this is not meant to introduce functional changes, so just go with it. On the bright side, the interactions are now clearer, so it could be made saner in the future. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
