[gtk/new-style-menu] box layout: Handle native children

    box layout: Handle native children
    
    These need to be skipped in measuring,
    and we need to call gtk_native_check_resize
    on them during allocation.
    
    This was showing up as the new-style
    context menu in widget-factory forcing
    its relative-to box to grow when its
    shown.
