Subject: feat: OpenTelemetry Tracing API and Exporting (#26710)

Initial import of OTEL code supporting tracing. Metrics soon to come.
Implements APIs for https://jsr.io/@deno/otel so that code using
OpenTelemetry.js just works tm.

There is still a lot of work to do with configuration and adding
built-in tracing to core APIs, which will come in followup PRs.
