Fix a QuicConnection connection close log

During IETF interop testing I realized that one of our logs was printing the decimal error code instead of the readable string. This CL fixes that to make debugging easier. It also removes the "private" special-casing which has been obsolete since we dropped support for T050. This change only modifies logging and therefore does not require flag protection.

QUICHE stands for QUIC, Http/2, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:
