Gtk overrides: make sure TreeModelSort.new_with_model and TreeModel.sort_new_with_model exist

In https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/1134 the method was changed to a constructor
which means the API is different between older and newer gtk.

Add fallbacks for both in our overrides so both ways work all the time.
