QUIC: allowed main QUIC connection for some operations. Operations like ngx_quic_open_stream(), ngx_http_quic_get_connection(), ngx_http_v3_finalize_connection(), ngx_http_v3_shutdown_connection() used to receive a QUIC stream connection. Now they can receive the main QUIC connection as well. This is useful when calling them from a stream context.
