Subject: [PATCH] Stabilize `cstr_count_bytes`

Newly stable API:

```rust
impl CStr {
    pub fn count_bytes(&self) -> usize;
}
```

Const stabilization has not yet been decided, so that will continue to be
gated under <https://github.com/rust-lang/rust/issues/113219>.

Fixes: <https://github.com/rust-lang/rust/issues/114441>
