Enable conditional checking of values in the Rust codebase This pull-request enable conditional checking of (well known) values in the Rust codebase. Well known values were added in https://github.com/rust-lang/rust/pull/94362. All the `target_*` values are taken from all the built-in targets which is why some extra values were needed do be added as they are not (yet ?) defined in any built-in targets. r? `@Mark-Simulacrum`
