[fedcm] Autofill emails only if the user accepts the modal dialog prompt

For verified email addresses, we'll show the FedCM modal dialog to get
some confirmation that the user wants to share their email address
(along with other fields, such as names and profile pictures).

When the modal dialog is shown, the user has the choice to reject or
dismiss it. When that happens, we want to make sure that the field does
not get auto-filled (in addition to failing the promise of the
conditional request).

For the password field recommendation, on the other hand, a modal isn't
necessary, and the token can be auto-granted without requiring extra
prompting.

To accomplish these differences, we introduce:

- A boolean parameter to OnFederatedTokenReceivedCallback, to let the
  browser and password autofill managers know if the request succeeded
- A boolean autogrant parameter to NotifyAutofillSuggestionAccepted to
  let the FederatedAuthAutofillSource know whether to request
  additional permission or not

And the necessary implementation in the FederatedAuthAutofillSource to
accomplish the semantics described above.
