Add support for exit spans in Code Origin for Spans

[watson]

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.

Do we already have a utility function that does this that I can re-use? Seem very much overkill to write this code for this test, but it does make the actual test much simpler to write once the tags are converted to a proper object structure 🤔
