Create a new rustls_client_cert_verifier_optional for the root store. The
verifier can be used in several rustls_server_config instances. Must be
freed by the application when no longer needed. See the documentation of
rustls_client_cert_verifier_optional_free for details about lifetime.
This copies the contents of the rustls_root_cert_store. It does not take
