Migrates the remaining crates to edition 2024. We like to stay on the latest edition if possible. There is no functional changes, however some code changes had to be done to accommodate the edition's breaking changes. Like the previous migration PRs, this is comprised of three commits: * the first does the edition update and makes `cargo check`/`cargo clippy` pass. we had to update bindgen to make its output [satisfy the requirements of edition 2024](https://doc.rust-lang.org/edition-guide/rust-2024/unsafe-extern.html) * the second commit does a `cargo fmt` for the new style edition. * the third commit reorders imports as a one-off change. As before, it is entirely optional. Part of #10918
