fix: `rustc_compile_action` emits `CcInfo` for `wasm32` targets (#1979)

This change allows `cc_binary()`, `cc_library()`, etc. targets to depend
on `rust_libary()`, `rust_static_library()`, etc. targets when targeting
`wasm32`.

# Nix
Nix Flake that declares developer tools when executing in a Nix environment.
This is kept in its own package so that when using the Nix `path:` syntax, only
this directory is copied to the Nix Store instead of the entire `rules_rust`
repository.
