Jacob Pratt 0c326ece10 Rollup merge of #155450 - safer-rust:fix-doc2, r=jhpratt ...

Remove unnecessary safety conditions related to unchecked uint arithmetic

Improve the safety documentation of three unsafe APIs related to unsigned integer arithmetic.

- [unchecked_add](https://doc.rust-lang.org/nightly/core/primitive.usize.html#method.unchecked_add): It is impossible for `self + rhs < usize::MIN`.
- [unchecked_sub](https://doc.rust-lang.org/nightly/core/primitive.usize.html#method.unchecked_sub): It is impossible for `self - rhs > usize::MAX`.
- [unchecked_mul](https://doc.rust-lang.org/nightly/core/primitive.usize.html#method.unchecked_mul): It is impossible for `self * rhs < usize::MIN`.

The examples use `usize` for demonstration. All unsigned integer types suffer from the same issue because their APIs are generated by the same macro `uint_impl`, and fixing the macro documentation will fix them all.
