[mutter/wip/carlosg/xdg-popup-grab-with-styli] wayland: Check stylus serials on meta_wayland_seat_can_popup()



commit aee8fb371f1399d45bc689b7930658a8736af0cf
Author: Carlos Garnacho <carlosg gnome org>

    wayland: Check stylus serials on meta_wayland_seat_can_popup()
    
    This allows xdg_popup.grab() to work with styli. Without this check
    we would bail out and emit xdg_popup.popup_done, leaving stylus users
    unable to interact with popup menus, comboboxes, etc...
    
    Closes: https://gitlab.gnome.org/GNOME/mutter/issues/886
