[Password Manager] Add flag whether |PasswordForm.all_possible_passwords| include autofilled value or its part

If any password field has autofilled value or its part, Chrome should request reauth when a user clicks the eye icon to reveal password(s).

[Password Manager] Hide the eye icon in a prompt for privacy reasons in some cases

Based on https://bugs.chromium.org/p/chromium/issues/detail?id=768742#c14, 
* manual fallback should have the eye icon iff the form doesn't contain autofilled value or its part.
* automatic prompt should have the eye icon iff the bubble is shown first time (i.e. right after submission). If the bubble was closed and re-opened again, the eye shouldn't be available.

In further CL, re-authentication will be implemented instead of icon hiding.
