[BottomNavigationView] Allow adding menu items without onItemsChanged being called

I want to add menu items to BottomNavigationView in code as their configuration is retrieved from the backend.
And that can be done like this:

bottomNavigationItems.forEachIndexed { index, item ->
    bottomNavigationView.menu.apply {
      add(0, item.menuId, index, item.title).apply {
        setIcon(item.icon)
      }
    }
  }

But when you do that, MenuBuilder.addInternal calls onItemsChanged requesting a relayout after each item is added with is only needed after the last item has been added.

To handle this, MenuBuilder has stopDispatchingItemsChanged.

But BottomNavigationMenu.addInternal prevents this, as it calls startDispatchingItemsChanged internally.

Comienza con BottomNavigationView y la ruta de BottomNavigationMenu.addInternal descrita en el issue; después, inspecciona cómo afectan MenuBuilder.stopDispatchingItemsChanged y startDispatchingItemsChanged a MenuBuilder.addInternal. Se considera completado cuando se pueden añadir varios elementos de menú sin solicitar un relayout después de cada adición, mientras que la adición final sigue actualizando la vista de navegación.
