The area source, window source, and monitor source, currently set up the stream size up front, given the area, maximum allowed window size or monitor resolution, but for to be introduced sources, the size will be negotiated using PipeWire, instead of specified via the D-Bus API. This commit changes the internal source API to allow for this. There are currently no users of this new behaviour. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1698>
