Rollup merge of #89335 - mbrubeck:range-is-sorted, r=cuviper
Optimize is_sorted for Range and RangeInclusive

The [`Step`] trait guarantees that `Range<impl Step>` yields items in sorted order.  We can override `Iterator::is_sorted` based on this guarantee, as we already do for `Iterator::min` and `max`.

Thank you to ``@fiveseven-lambda`` who pointed this out [on the Rust Users Forum](https://users.rust-lang.org/t/is-sorted-method-in-impl-iterator-for-range/64717).
