At the end of the remote consent flow, the browser makes the second
issueToken request. This request must use a login token of an account
that the user has chosen in the consent UI. Gaia returns an id of this
account in a consent result.

This CL updates IdentityGetAuthTokenFunction to use the id returned in a
consent result instead of the one that was originally chosen by Chrome.

This CL also moves IdentityTokenCacheValue to use static factory methods
instead of multiple constructor overloads. This makes obvious what type
of a cache value is created instead of relying on argument types.
