workspace: Use the new WorkspaceLayout for allocating window clones
Switch to the new WorkspaceLayout layout manager to allocate the window clones of the overview properly using Clutters layouting mechanisms. Since we now no longer make use of the fullGeometry, we can remove the setFullGeometry() function from the Workspace class. Also we can stop setting the actualGeometry on the Workspaces and WorkspaceViews and instead just set the fixed position and size of the views to their full or actual geometry. This also has the benefit that we no longer have to set a custom clip, but can simply enable clip_to_allocation. The geometry needs to be set inside a BEFORE_REDRAW later because _updateWorkspacesActualGeometry() is called from a notify::allocation handler. This isn't doing any animations when showing/hiding the overview yet, we'll add that in the next commit. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1305
