_menu_append_contextual_items()

Account for menu items that are only defined at certain paths, so will not be cached.

We don't support the full range of menu item options for these menu items. We don't support MENU_VISIBLE_IF_HAS_CHILDREN, and we require parent items to be declared before their children.
