[QUIC] Surface transport error code in QuicException

[ManickaP]

In case of SHUTDOWN_INITIATED_BY_TRANSPORT we now get transport level error code, but we don't use it.

We also get it in SHUTDOWN_COMPLETE.ConnectionShutdown case where we would throw the same exception as in SHUTDOWN_INITIATED_BY_TRANSPORT in ideal case.

There might still be necessity to expand msquic data to avoid holding stream -> connection link to solve this properly.

Triage: in the same bucket as other exception related issues, should be investigated and decided in 8.0.

@wfurt shouldn't this be resolved by your changes?
