Auto merge of #125434 - nnethercote:rm-more-extern-tracing, r=jackh726

Remove more `#[macro_use] extern crate tracing`

Because explicit importing of macros via use items is nicer (more standard and readable) than implicit importing via `#[macro_use]`. Continuing the work from #124511 and #124914.

r? `@jackh726`
