[mutter/wip/carlosg/there-can-be-only-one: 21/23] backends: Add private call to update MetaBackend from a device

[Carlos Garnacho <carlosg src gnome org>]

commit 3c1aae0e17748530877031d10634e2737891d649

    backends: Add private call to update MetaBackend from a device
    
    We update some details like the last used device and pointer visibility
    from events, but this is done inconsistently on X11 since the
    ClutterEvents are created and pushed from an additional place.
    
    Make these updates happen on a private call, that will be called from
    these places in X11.
