wayland: Simplify MetaSelectionSourceWayland

Browse Source 
Instead of taking resource and send/cancel funcs, take a
MetaWaylandDataSource, which exposes all the vfuncs to do the same on the
internal resource.

This has the added side effect that only MetaWaylandDataSource has a
pointer to the wl_resource, which may be unset untimely.

Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
