[mutter/wip/tablet-protocol-v2: 24/70] clutter: Add ::n-rings and ::n-strips property to ClutterInputDevice

[Carlos Garnacho <carlosg src gnome org>]

commit 47ff0d7129c8e14c61f8cdfc3c68875a2b44dbd0

    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.
