LibGUI: Add MenuBar::add_menu(name)

This allows us to construct menus in a more natural way:

    auto& file_menu = menubar->add_menu("File");
    file_menu.add_action(...);

Instead of the old way:

    auto file_menu = GUI::Menu::construct();
    file_menu->add_action(...);
    menubar->add_menu(file_menu);
