w3c phase 2: add last parent_id to tracestate

[mabdinur]

What does this PR do?

With this change span_id will be encoded in both the tracestate and traceparent headers. This will allow us to re-connect datadog traces that contain non-datadog spans.

Ex: Host A: Datadog Spans ->tracecontext-> Host B: Otel Dynatrace Spans -->tracecontext-> Host C: Otel Datadog Spans By adding span_id to the tracestate Host C will be able to detect upstream Datadog spans from Host A. This span_id will then be sent to Datadog intake services (via _dd.parent_id tag). The Datadog internal services will use this tag to reconnect Datadog Spans.

Tests will be added in this PR: https://github.com/DataDog/system-tests/pull/2181
