Add initial Rust rules to Bazel.

Todo:
* Implement rust_bench_test for running benchmarks
* Enable rust_test to depend solely on a rust_library (since many projects
  intermix #[test] methods in lib source).
* Improve error checking and handling and prevent rust_binary from directly
  depending on cc_library.
* Implement rust_doc for generating rustdoc.
