QUIC: idle mode for main connection.
Now main QUIC connection for HTTP/3 always has c->idle flag set. This allows
the connection to receive worker shutdown notification. It is passed to
application level via a new conf->shutdown() callback.
The HTTP/3 shutdown callback sends GOAWAY to client and gracefully shuts down
the QUIC connection.
