Move impl of identity.GetProfileUserInfo() extension API to its own file

Move impl of identity.GetProfileUserInfo() extension API to its own file

As a precursor to a refactoring of the identity extension API implementation
to use the Identity Service, I am moving the implementations of the six
identity extension API functions to their own files, rather than all
being lumped together in identity_api.*. This will make it easier to
analyze each of these function implementations independently and
incrementally convert them to use the Identity Service.

Of note: This CL makes a minor code change to eliminate usage of the
GetPrimaryAccountId() helper function defined in identity_api.cc.
The new code is functionally equivalent to the old code: both are
effectively AccountTrackerService::GetAccountInfo(
    SigninManager::GetAuthenticatedAccountId()), wherein the
AccountTrackerService and SigninManager instances are the ones
corresponding to the Profile in question.
