Interoperation between wl_data_device_manager v1 and v3 got broken at some point. Ensure that we resort to the "copy" action if either the drop site or the drag source are from a client that requested v1. Closes: https://gitlab.gnome.org/GNOME/mutter/issues/965 (cherry picked from commit ffad55c66f5b131cdaa92ef61c44d99b7c7312b5)
