build-support/rust: Organize

- `toRustTarget` and friends pulled out from rust tools into rust library. Since they don't depend on any packages they can be more widely useable. - `build-rust-package` gets its own directory - `fetch-cargo-tarball` gets its own directory (cherry picked from commit 18ed048c7b27e288a6c9ba894790a7e67ed5080d)
