Owen Lin 20f2a216df feat(core, tracing): create turn spans over websockets (#14632) ...

## Description

Dependent on:
- [responsesapi] https://github.com/openai/openai/pull/760991 
- [codex-backend] https://github.com/openai/openai/pull/760985

`codex app-server -> codex-backend -> responsesapi` now reuses a
persistent websocket connection across many turns. This PR updates
tracing when using websockets so that each `response.create` websocket
request propagates the current tracing context, so we can get a holistic
end-to-end trace for each turn.

Tracing is propagated via special keys (`ws_request_header_traceparent`,
`ws_request_header_tracestate`) set in the `client_metadata` param in
Responses API.

Currently tracing on websockets is a bit broken because we only set
tracing context on ws connection time, so it's detached from a
`turn/start` request.
