We only implemented Clone on `extern "Rust" fn`s (for up to 8 parameters). This didn't cover `extern "C"` or `unsafe` (or `unsafe extern "C"`) `fn`s, but there's no reason why they shouldn't be cloneable as well. The new impls are marked unstable because the existing impl for `extern "Rust" fn`s is. Fixes #24161.
