[mutter/wip/carlosg/there-can-be-only-one: 149/151] backends: Add private call to update MetaBackend from a device

[Carlos Garnacho <carlosg src gnome org>]

commit c9c7bde6068f13688ff30fca192ad81ed2d4068c

    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.
