Motivation
It was failing to compile if axum-core's tracing feature was enabled, but the tracing feature of axum or axum-extra wasn't when those were part of the dependency tree.
Solution
Use a private re-export, as commonly done with macros that need to refer to some other crate at the expansion site.
Fixes #2932.
