drm/xe/rtp: Add match on any GT

One surprising factor of GRAPHICS_VERSION()/MEDIA_VERSION() matching for
people adding new WAs is that it implicitly checks that the
graphics/media IP under check is of that specific type and not that the
device contains a media/graphics IP of that version. Add a new
*_ANY_GT() variant that can be used in that case.
