[mutter] remote-desktop/session: Add CapsLockState and NumLockState properties

[Marge Bot <marge-bot src gnome org>]

    remote-desktop/session: Add CapsLockState and NumLockState properties
    
    Will be used by remote desktop services that want to try to affect the
    end result of these. We cannot let it set these directly, as these needs
    to be done using virtual key events to not cause issues in all the XKB
    state tracking, so remote desktop services try to deal with this
    themself if they need to.
    
    Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1342
    Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1739>
