This PR fixes issue #3247 by normalizing the CARGO_MANIFEST_DIR path in cargo_build_script to ensure it doesn't end with trailing slashes.
The issue occurs because CARGO_MANIFEST_DIR in cargo_build_script doesn't clean the path like in rust.bzl and rustc.bzl, leading to inconsistent paths that can cause problems for build scripts.
