folly::IOBuf does not have TreeBuilder v2 container support. Add it. The implementation is a direct clone of v1. It still lacks tests. Test Plan: - It codegens on a prod type. - No runtime testing... Bad form, I know. - Issue created to add integration tests: https://github.com/facebookexperimental/object-introspection/issues/436
