Any way to enable stack trace for spans?

[kohdan]

Currently the generated code has defer span.End(), but I would like it to be defer span.End(trace.WithStackTrace(true)) so that I can get stack traces from panics.

I couldn't find any configuration in ogen generation and it seems like there's no way to set it outside of the generated code. For example, using otelhttp.WithSpanOptions() for configuring otelhttp.NewHandler doesn't work since it only accepts trace.SpanStartOptions and not trace.SpanEndOptions.
