Add a flag for fill on account select without highlighting

Add a flag for fill on account select without highlighting

In the fill on account select password manager experiment, the enabled
setting still highlights the fields that can be autofilled. This adds an
experimental group where the fields will not be highlighted even if they
can be autofilled until after a choice has been selected.

Garrett, can you take a look at this? In an offline discussion, rolfe@ suggested
a second group for the experiment where we don't highlight the autofillable
fields at all until a choice has been made from the menu.
