Expose the peer ephemeral public key used for TLSv1.3 key exchange.

SSL_get_server_tmp_key() provides the peer ephemeral public key used
for key exchange. In the case of TLSv1.3 this is essentially the peer
public key from the key share used for TLSv1.3 key exchange, hence make it
availaable via SSL_get_server_tmp_key().
