Change right_click_menu from deepin_menu.menu to normal Qml Menu, so that:
1. Show the Preferences dialog.
2. Starts Removing the dependence of deepin_menu. I can't understand why deepin-movie needs a menu service.

Next step:
1. Should we change right_click_menu to DMenu/DMenuItem?
2. What's the difference of Menu and DMenu? I guess Menu+CSS=DMenu.
3. Can we remove the dependence of deepin-qml-widgets, replace them with CSS?
