AboutSigninInternals: remove the SigninManagerBase::Observer dependency

It can observe IdentityManager::Observer instead. This is a step
forward in the migration to IdentityManager API.

Most usages of SigninManager were also replaced by their equivalent
IdentityManager API. It's also observing
IdentityManager::DiagnosticsObserver from now on.

BUG: 809539
