Original change's description:
> Create ExternalAuthGoogleDelegate
>
> * Create ExternalAuthGoogleDelegate, owned by ExternalAuthUtils, which
>   will be used to implement isGoogleSigned downstream, rather than doing
>   so with an overriding subclass.
> * This is patch 1/5 for providing ExternalAuthUtils as a singleton
>   instead of from AppHooks.
