wayland: Add MetaWaylandXdgSessionState
This object is a windowing-specific implementation of MetaSessionState, allowing to save window state for toplevel surfaces of a Wayland client using the xdg_session_management_v1 protocol. This object is detached from windowing logic itself, and will be integrated in later commits. Changes from Carlos Garnacho: Integrate state serialization with MetaSessionState and MetaSessionManager. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3825>
