Backport of #101250

Fixes#101233.
Fixes#100971.
Contributes to #101463

Customer Impact

Customers may encounter a deadlock when attempting to open an outbound QuicStream and the peer closes the connection at the same time.

Regression

No

Testing

Functional tests as part of CI.
Deadlock scenario tested locally by modifying the timing of the operations to make the deadlock more likely.

Risk

Low, issue is well understood and fix affects only code path for opening an outbound QuicStream, which is covered extensively by functional tests.
