`alias_rules.bzl` references `rules_cc`

https://github.com/bazelbuild/rules_rust/blob/8798aca336b58bfe6ce70265e05fa09257a7b86a/extensions/wasm_bindgen/3rdparty/crates/alias_rules.bzl#L3-L11

This means that all consumers of `rules_rust` that vendor crates into their repo must depend on `rules_cc`. Instead this behavior should probably be hidden in `rules_rust` so it's the only module consumers need to specify.
