chore: consolidate workspace settings

* Move common workspace settings to the `[workspace]` sections in the root.
* Remove Cargo settings that are identical to the defaults (per Cargo [recommendations](https://doc.rust-lang.org/cargo/reference/manifest.html))
* Add common clippy lint configuration
