[Nitro] Use tracing channels for `db0`

[logaretm]

Following our discussion with Pi0, we wanted to see the feasibility of using tracing channels for db0 instead of our hacky rollup magic approach.

This can be useful for other frameworks making use of db0. We are working on getting that shipped in db0 package itself.

This issue is tracking the discussion here.
