🍝🏠 Refactor MostVisited UI management, extract it for reuse in Home.
* Tile is MostVisitedItem stripped of logic, just a data holder.
* TileGroup implements MostVisitedURLsObserver and is extracted from NewTabPageView.
* TileGroup.Delegate replaces MostVisitedItemManager and bits of NewTabPageManager.
* TileGroupDelegateImpl is extracted from NewTabPageManagerImpl.
* TileGroup.Observer allows custom actions to be taken for certain events in TileGroup.
* TileGrid and NewTabPageView now have a TileGroup.
