Rollup merge of #78627 - est31:total_cmp_no_superset, r=m-ou-se
Point out that total_cmp is no strict superset of partial comparison Partial comparison and total_cmp are not equal. This helps preventing the mistake of creating float wrappers that base their Ord impl on total_cmp and their PartialOrd impl on the PartialOrd impl of the float type. PartialOrd and Ord [are required to agree with each other](https://doc.rust-lang.org/std/cmp/trait.Ord.html#how-can-i-implement-ord).
