We've been observing some performance issues using crate_universe on CI. Therefore, we're moving to vendor the auto-generated BUILD files in our repository. This should provide a nice speed boost, while getting rid of the complexity of the "rust cache" job we've been using when we had a lot of git dependencies. This PR includes a vendor script, and I'll put up a CI job internally that runs that vendor script on Cargo.toml and Cargo.lock changes, to check that the vendored files are in sync.
