Disallow shebang in `--cfg` and `--check-cfg` arguments This PR is similar to https://github.com/rust-lang/rust/issues/146130, where we disallowed frontmatter in `--cfg` and `--check-cfg` arguments. While fixing the other one we also discovered that shebang `#!/usr/bin/shebang` are currently also allowed in `--cfg` and `--check-cfg` arguments. Allowing shebang in them (which are just ignored) was never intended, this PR fixes that by not stripping shebang for `--cfg` and `--check-cfg` arguments. This is technically a breaking-change, although I don't expect anyone to actually rely on this unintended behavior.
