OneGoogleBar on local NTP: Use cookie auth instead of OAuth2

This is achieved by talking to a different endpoint for fetching the
OGB sources, which accepts cookies. As a consequence, the cached data
is now cleared when the Gaia cookies change, rather than when the
SigninManager state changes.

This makes the OneGoogleBar use Chrome's UI language, to be consistent
with the rest of the local NTP.

OneGoogleBarService: don't notify on signin state change if cache is empty

A change to the signin state causes the OneGoogleBarService to clear its
cache. If the cache was already empty before, there is no need to notify
observers. This fixes a bug where the One Google Bar sometimes doesn't
appear on the first NTP right after Chrome startup, where the following
happened:
- LocalNtpSource calls OneGoogleBarService::Refresh.
- Before the request completes, the service gets a signin change
  notification (maybe because some cookies got loaded from disk?) and
  tells the LocalNtpSource "there's no OGB right now".
- The request finishes successfully, but the NTP has already gotten the
  "no OGB" notification.
