[mutter/wip/carlosg/no-toggle-panel-across-focus: 4/5] wayland: Only enable OSK if receiving .enable when already active

    wayland: Only enable OSK if receiving .enable when already active
    
    Enable the OSK if receiving .enable consecutively (i.e. the
    ClutterInputFocus was already focused). We specifically want to avoid
    enabling the panel just because of focus changes within a surface (where
    the .disable request across focus change would previously unfocus the
    ClutterInputFocus). Prior state should be preserved if possible in that
    situation.
