Rollup merge of #102030 - est31:tidy_walk_no_reexport, r=Mark-Simulacrum

Don't crate-locally reexport walk functions in tidy

I've moved the walk functions into their own module in #100591 and didn't want to make changing the paths everywhere in tidy part of the PRs diff, so I just reexported the functions locally. This PR removes the crate-local reexport and instead does module level reexports. I'm not sure how much it's worth it and whether the new state is better, idk. Feel free to have any opinion on this.
