What does this PR do?

Note: This PR relates to an upcoming Datadog feature that's not generally available yet.

Support for Code Origin for Spans was added in #4449. That PR laid the groundwork for supporting this new feature and added limited support for just Fastify entry-spans. This PR adds to that original PR by adding support for all exit-spans. That is, spans that record a request going out to a different service, e.g. a database request, an outgoing HTTP request etc.

To enable, set DD_CODE_ORIGIN_FOR_SPANS_ENABLED=true.
