Record if the smart bubble suppresses credentials.

In PasswordManager.FillingAssistance we record whether the user was
supported at logging into a site. One case is that this is not happening
because the user has no saved credentials. This CL introduces an enum to
indicate that there are no saved credentials and the user does not get offered
to save them anymore.
