Improve OpenTelemetry Context Propagation Across Threads

Improve the tracing (OpenTelemetry) context propagation across threads. #39010 (Frank Chen).
Enhanced OpenTelemetry tracing context propagation across threads in ClickHouse.

Why it matters

This feature improves the propagation of tracing context when executing operations across multiple threads, ensuring more accurate and comprehensive distributed tracing data. It solves the problem of lost or inconsistent tracing information in multi-threaded environments, enhancing observability and debugging capabilities for users.

How to use it

Users benefit from this enhancement automatically without additional configuration when utilizing OpenTelemetry tracing in their ClickHouse deployments. No extra steps are required to enable improved context propagation.
