In preparation for the new element `GstGtkWaylandSink`, move reusable parts out of `GstWaylandSink` into the already exisiting but very barebone library. Notable changes include: - the `GstWaylandVideo` interface was dropped - support for `wl-shell` was dropped - lots of renaming in order to match established naming patterns - lots of code modernisations, reducing boilerplate - members were made private wherever possible Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2479>
