`embassy-usb-driver`: add release automation using `cargo-release`

this requires you to install [`cargo-release`].
note that this does not include a URL pointing to the diff on GitHub as
is usually done in changelogs since `embassy` is a mono-repo and the GH
UI doesn't offer a commit view per folder (see the [GH feature request]
for this).

[`cargo-release`]: https://crates.io/crates/cargo-release
[GH feature request]: https://github.com/orgs/community/discussions/162131
