Add an OpenTelemetry direct-style tracing interceptor

[adamw]

Introduce a new module, tracing/opentelemetry-tracing-sync, which should include integration with OT's tracing: reading the context from the request and propagating it downstream.

The approach should target "direct-style" (that is, the Identity "effect type"), and be compatible with Loom/Ox, that is with virtual threads & scoped values. Note that the the OT Java libraries often rely on ThreadLocals, which are not Loom-compatible.

The solution should work in conjunction with softwaremill/sttp#2314

@adamw #4122

I just made initial changes long before for this issue which I think we primarily need to work on in sttp(softwaremill/sttp#2314 ) and need to test and evaluate my approach. Just thought to complete them (#4057 and https://github.com/softwaremill/sttp/issues/2292one by one rather than solving this set of issues (refactor of OT and this tracing/opentelemetry-tracing-syn issues simultaneously
