Use associated items of `char` instead of freestanding items in `core::char`

The associated functions and constants on `char` have been stable since 1.52 and the freestanding items have soft-deprecated since 1.62 (rust-lang#95566). This PR ~~marks them as "deprecated in future", similar to the integer and floating point modules (`core::{i32, f32}` etc)~~ replaces all uses of `core::char::*` with `char::*` to prepare for future deprecation of `core::char::*`.

Document `PointerLike`

I forgot to document this, and even though it's currently more of an implementation detail, the old doc was kinda embarrassing 😅
