Revert my recent changes regarding title directionality.

This reverts:
  r82400: Plumb direction of document title through IPC layer.
  r82582: Add and use a base::i18n::StringWithDirection for carrying titles.
  r82778: Change NavigationEntry's title fields to carry the text direction.

I'm going to take an alternative approach; after getting this far, I can
see that this approach was too complicated.
