Migrate `rustc_ty_utils` to `SessionDiagnostic` I have migrated the `rustc_ty_utils` crate to use `SessionDiagnostic`, motivated by the [recent blog post about the diagnostic translation effort](https://blog.rust-lang.org/inside-rust/2022/08/16/diagnostic-effort.html). This is my first PR to the Rust repository, so if I have missed anything, or anything needs to be changed, please let me know! 😄 `@rustbot` label +A-translation
