Just wondering where there is a plan to support brpc on HTTP/3 or QUIC. It looks like the new HTTP3 protocol has some good features.

**Additional context/screenshots (更多上下文/截图)**

The issue names no files, tests, or implementation entry points. First determine brpc’s existing protocol support and define the intended HTTP/3 or QUIC scope; done would require an agreed support plan and implementation criteria.
