[mutter] window: Merge got_focus/lost_focus to a new function

[Jasper St. Pierre <jstpierre src gnome org>]

    window: Merge got_focus/lost_focus to a new function
    
    Make it a static function for now, but this will be a private
    function soon, replacing meta_window_lost_focus. This should
    contain no functional changes, only cosmetic indentation changes,
    so best viewed with ignorews=1 or -w or -b, you know the drill.
