[bazel][rust] Add crates_vendor target

This target will be used to generate BUILD.bazel files for Rust
libraries in third_party/rust_crates.

Users are not expected to build this target directly. Instead, they
will keep invoking `fx update-rustc-third-party`, which takes care of
laying out a Bazel workspace and invoke this target there.

This setup uses the following vendored/prebuilt tools:

* bazel
* buildifier
* Rust toolchain (rustc, cargo, etc.)
* rules_rust

Bazel will fetch other dependencies from upstream, this includes Rust
crates needed to bootstrap crates_vendor (build the cargo_bazel binary).

This only supports running on Linux hosts.

Fixed: 358312539
