        Implements support for _NET_WM_ALLOWED_ACTIONS.
        Fixes #84282.

        * src/display.[ch]: (meta_display_open): add
        _NET_WM_ALLOWED_ACTIONS atoms.

        * src/screen.c: (set_supported_hint): set them
        as being supported.

        * src/window.c:
        (set_allowed_actions_hint): impl setting
        _NET_WM_ALLOWED_ACTIONS.
        (recalc_window_features): use it here, but only
        if things have changed.
