    core: Update frame style when _GTK_THEME_VARIANT changes
    
    When the _GTK_THEME_VARIANT property changes, rather than just
    updating the window's theme_variant property, update its frame
    style as well, so that the window decoration reflects the requested
    variant. As the initial properties of a window may be read before
    its frame is created, there will be cases where the change is not
    picked up initially.
