Joe Groff df3f332f9d IRGen: Hide type metadata records for noncopyable types from discovery by existing runtimes. ...

We'd still like to try to be forwardly compatible with future runtimes
that do properly handle noncopyable types, so emit them in a separate section from
copyable type records for now. This should prevent `_typeByName` from letting
someone get a hold of a noncopyable type's metatype as a (copyable) `Any.Type` and
then trying to use it to copy uncopyable values.
