    wayland: Make it possible to trigger popups through pointer/keyboard/touch
    
    Right now we just check the pointer serial, so the popup will be
    immediately dismissed if the client passes a serial corresponding to
    another input device.
    
    Abstract this a bit further and add a meta_wayland_seat_can_popup() call
    that will check the serial all input devices. This makes it possible to
    trigger menus through touch or keyboard devices.
