Customer Impact
An unexpected HTTP/3 connection error could put Kestrel into a retry loop. HTTP/3 connections will stay open forever, throwing errors and consuming CPU. An example of an unexpected error is being fixed in runtime dotnet/runtime#60244.
This PR adds an additional safeguard to Kestrel so that a connection will be aborted if there is an unexpected error. This ensures the connection immediately exits instead of going into a retry loop.
Testing
Manual testing. Confirmed that a HTTP/3 connection is aborted when there is an unexpected exception.
Risk
Low. The new logic is only for HTTP/3, and is only executed when there is an HTTP/3 connection error.
