We discussed having TabModel getting it's WebStateList from a Browser object in
the old architecture. This means that TabModel will need to know about Browser
(or the class creating the TabModel) which is not yet building with ARC.

I think using base::scoped_nsobject<> here will allow this without requiring
converting TabModel to ARC.

   ios::ChromeBrowserState* browser_state_;
   std::unique_ptr<WebStateListDelegate> web_state_list_delegate_;
   std::unique_ptr<WebStateList> web_state_list_;
