Move UbertokenFetcher from //chrome to //google_apis.

This CL eliminates //chrome- and //content-level dependencies from
UbertokenFetcher and moves it to //google_apis/gaia. Notable changes:
- Change UbertokenFetcher to take in the OAuth2TokenService and
  URLRequestContextGetter to use rather than the Profile.
- Add a FakeOAuth2TokenService to enable moving the UbertokenFetcher unittest
  away from using FakeProfileOAuth2TokenService.
