Make most std::ops traits const on numeric types

This PR makes existing implementations of `std::ops` traits (`Add`, `Sub`, etc) [`impl const`](rust-lang#67792) where possible.
This affects:
- All numeric primitives (`u*`, `i*`, `f*`)
- `NonZero*`
- `Wrapping`

This is under the `rustc_const_unstable` feature `const_ops`.
I will write tests once I know what can and can't be kept for the final version of this PR.

Since this is my first PR to rustc (and hopefully one of many), please give me feedback on how to better handle the PR process wherever possible. Thanks

Fix incorrect doc link

Looks like a copy paste mistake

Unify titles in rustdoc book doc attributes chapter

As discussed in rust-lang#90339.

I wasn't able to find out where the link to the titles was used so let's see if the CI fails. :)

Make `core::slice::from_raw_parts[_mut]` const

Responses to rust-lang#90012 seem to allow ``@rust-lang/wg-const-eval`` to decide on use of `const_eval_select`, so we can make `core::slice::from_raw_parts[_mut]` const :)

---
This PR marks the following APIs as const:
```rust
// core::slice
pub const unsafe fn from_raw_parts<'a, T>(data: *const T, len: usize) -> &'a [T];
pub const unsafe fn from_raw_parts_mut<'a, T>(data: *mut T, len: usize) -> &'a mut [T];
```
