fix(node): Ensure fetch/http breadcrumbs are created correctly

[mydea]

This PR ensures that (node) fetch and http requests generate breadcrumbs correctly, even if tracing is disabled.

It also adds tests for this, and ensures we pass the request/response to the hint correctly.

Fixes #12132

[AbhiPrasad]

Can we add a test?

This should also be added to the httpIntegration?

Did that! And actually noticed this was fundamentally flawed, and tied to the http.client spans - so it was not working at all without performance 😬 so I adjusted all of this for fetch and http to ensure we always get breadcrumbs, and added tests for this.
