[ios] Updates the incognito ui to use a UIStackView.

UIStackView automatically positions views in a vertical column, which allows us
to remove a number of positioning constraints.  This also makes it possible to
change individual pieces of the incognito ui without needing to modify any
constraints.

BUG= 805521

How is this one going? It seems to be the largest task in the Incognito user story and it's not assigned. 

Screenshots attached for what will be in the first CL.
