[mutter] clutter: Add ::n-rings and ::n-strips property to ClutterInputDevice

[Carlos Garnacho <carlosg src gnome org>]

    clutter: Add ::n-rings and ::n-strips property to ClutterInputDevice
    
    This will only be practical for pads (and maybe generic buttonsets in
    the future?), we just need to know the number as the events will also
    contain a number as the identificator.
