Set clippy lints in workspace (requires rust 1.74) (#2390)

We currently use a bit of a hack in `.cargo/config` to make sure that
clippy isn't too annoying by specifying the list of lints.

There is now a stable way to define lints for a workspace. The only down
side is that every crate seems to have to opt into this so there's a
*few* files modified in this PR.

Dependencies:

- [x] PR that upgrades CI to use rust 1.74 is merged.
