Add start time on perf trace because it seems some steps haven't been recorded. (#35282) ...

The new trace log looks like
```
http start=2025-08-14 15:03:04 duration=0.6978s http.route=/
  http.func start=2025-08-14 15:03:04 duration=0.6978s func=common.ForwardedHeadersHandler.ForwardedHeaders
    http.func start=2025-08-14 15:03:04 duration=0.6978s func=routing.(*requestRecordsManager).handler-fm
      http.func start=2025-08-14 15:03:04 duration=0.6978s func=gzhttp.NewWrapper
        http.func start=2025-08-14 15:03:04 duration=0.6975s func=session.Sessioner
          http.func start=2025-08-14 15:03:04 duration=0.6973s func=context.Contexter
