[HTTP/3] Better handle connection close by browser

[JamesNK]

When a browser is closed it shuts down the QUIC transport rather than aborting. That leaves unidirection control streams in an unhealthy state.

• Need to shutdown the connection with the minimum of errors and error logging.
• Skip writing GOAWAY frame if the transport is dead

We need to know whether a connection was aborted or shutdown which will require work in System.Net.Quic.

Example logs from browser close:
