workspace: Track windows in WindowClone layout manager
Move the tracking of the bounding box and all the layout related things out of the WindowClone class and into the layout manager. This allows the layout manager to keep track of its windows itself and simply notify the new bounding-box property in case that box changes. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1297
