Rollup merge of rust-lang#59444 - cuviper:steps_between, r=scottmcm
Implement useful steps_between for all integers We can use `usize::try_from` to convert steps from any size of integer. This enables a meaningful `size_hint()` for larger ranges, rather than always just `(0, None)`. Now they return the true `(len, Some(len))` when it fits, otherwise `(usize::MAX, None)` for overflow.
