menu: lazily generate menu scenes
This removes the need to call update_client_list_combined_menu()
and update_client_send_to_menu() every time a root menu is opened.
This commit also fixed the incorrect menu position with following
configuration:
<menu id="foo" label="foo">
<item label="aaaaaa"/>
<item label="bbbbbb"/>
</menu>
<menu id="root-menu">
<menu id="foo" />
<menu id="foo" />
</menu>
