Title: Add Support for traceresponse Header in OpenTelemetry Tracing

Description:

I propose adding traceresponse headers, as defined by the Trace Response Header Specification, when OpenTelemetry tracing is enabled.

I didn't find any references to this header in the documentation: Tracing and OpenTelemetry tracer (proto).

I'm interested to know if there is an existing mechanism that automatically adds this header, or if there is any ongoing development for this feature. If not, I would like to suggest its implementation.

The benefit of this feature would be to pass the trace information to the calling client, even if the client did not originally set up the trace, allowing the client to use the trace ID for troubleshooting purposes.

add @AlexanderEllis @yanavlasov based on CODEOWNER

Also, add @joaopgrassi and @wbpcode as you worked on opentelemetry tracer in the past (e.g., #29207)

I believe this needs to be first defined in the OTel specification, before implementations start adding it. There's already an issue open in the OTel spec repo: open-telemetry/opentelemetry-specification#1355
