    efl_ui_focus_composition: introduce dirty and prepare
    
    this can be used in a container that has his own item management api,
    Each item management call results in a dirty call, once we are called to
    prepare for logical movement we can simply flush the order. So we reduce
    the spam of order calls, which also safes runtime.
