Migrate iOS' AuthenticationService classes

This is a first step in the migration of the different iOS'
authentication_service_* classes to the IdentityManager API. The
migration cannot be completed at this point as several APIs are not
available yet. This CL is basically passing the IdentityManager to the
different classes and using its API whenever appropiate instead of
directly calling SinginManager and TokenService.

Convert iOS AuthenticationService classes to IdentityManager

This is a follow up of crrev.com/c/1335567. The only missing bit
pending to be migrated was some SigninManager API that is now replaced
by the PrimaryAccountMutator API.
