Implement tracing-log on core dynamic metadata

And now we reach the point of this commit series. tracing-log is now capable of implementing its dynamic metadata resolution on solely publicly available APIs*, and thus so can anyone else do the same. *Dispatch still uses #[doc(hidden)] APIs to create the value set. Figuring out how to best expose is still an open question.
