[ios] Add tablet fake omnibox scroll animation with toolbar omnibox.

Adding a delegate method to update the tablet toolbar omnibox view
as the NTP is scrolled.  The bulk of the changes here are to rename
IncognitoViewControllerDelegate to NewTabPageControllerDelegate and
the new piping to add the toolbar delegate.
