Fix `rustc_parse_format` spans following escaped utf-8 multibyte chars Currently too many skips are created for char escapes that are larger than 1 byte when encoded in UTF-8, [playground:](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=c77a9dc669b69b167271b59ed2c8d88c) ```rust fn main() { format!("\u{df}{a}"); format!("\u{211d}{a}"); format!("\u{1f4a3}{a}"); } ``` ``` error[[E0425]](https://doc.rust-lang.org/stable/error-index.html#E0425): cannot find value `a` in this scope --> src/main.rs:2:22 | 2 | format!("\u{df}{a}"); | ^ not found in this scope error[[E0425]](https://doc.rust-lang.org/stable/error-index.html#E0425): cannot find value `a` in this scope --> src/main.rs:3:25 | 3 | format!("\u{211d}{a}"); | ^ not found in this scope error[[E0425]](https://doc.rust-lang.org/stable/error-index.html#E0425): cannot find value `a` in this scope --> src/main.rs:4:27 | 4 | format!("\u{1f4a3}{a}"); | ^ not found in this scope ``` This reduces the number of skips to account for that Fixes https://github.com/rust-lang/rust-clippy/issues/9727
