Unrolled build for rust-lang#128240

Rollup merge of rust-lang#128240 - mbrubeck:patch-3, r=joboet

Add links from `assert_eq!` docs to `debug_assert_eq!`, etc.

This adds information and links from the docs for the following macros to their debug-only versions:

* `assert_eq!`
* `assert_ne!`
* `assert_matches!`

This matches the existing documentation for the `assert!` macro.
