Revert "Move some deny attributes to Cargo.toml. (#4474)" (#4491)

## Motivation

#4474 doesn't actually work: We have to add `lints.workspace = true` to
all `Cargo.toml`s. And if I do that, there are _lots_ of errors.

## Proposal

Revert this for now. I will try again later, and also add the missing
comments.

## Test Plan

This only reverts an earlier PR.

## Release Plan

- Nothing to do / These changes follow the usual release cycle.

## Links

- Reverts #4474.
