This PR improves the ambiguous_wide_pointer_comparisons lint compare diagnostics: cmp/partial_cmp, but also the operators </>/>=/<=, by:

  1. removing the reference to std::ptr::addr_eq which only works for equality
  2. and adding an #[expect] suggestion for keeping the current behavior

Fixes #141510
