Shutdown Stream on Send/Start Failure

[nibanks]

Description

Fixes #3638 and #3639. In the rare case (OOM) that stream start fails when you use the QUIC_SEND_FLAG_START flag, it should be delivering a shutdown complete event to indicate this failure to start. Also fixes more event issues in the case of OOM in the send flush operation alloc path.

Testing

Existing automation and manual testing from original bug opener.

there's a build error. Finding the error in the github action is like finding a needle in a haystack. The console coloring is all gone.

/home/runner/work/msquic/msquic/src/core/connection.c:1873:9: error: too few arguments to function ‘QuicConnShutdown’

Feel free to push a fix, otherwise I will tomorrow.

May need to add 3 unit test cases to cover the following:

• If StreamSend returns SUCCESS, SEND_COMPLETE must be indicated exactly-once
• If StreamSend returns FAIL, SEND_COMPLETE must not be indicated.
• If StreamSend(QUIC_SEND_FLAG_START) returns SUCCESS, STREAM_SHUTDOWN_COMPLETE must be indicated exactly-once.
