This PR removes the public Deno.tracing.Span API. We are not confident we can ship an API that is better than the `@opentelemetry/api` API, because V8 CPED does not support us using `using` to manage span context. If this changes, we can revisit this decision. For now, users wanting custom spans can instrument their code using the `@opentelemetry/api` API and `@deno/otel`. This PR also speeds up the OTEL trace generation by a 30% by using Uint8Array instead of strings for the trace ID and span ID.
