Auto merge of #42167 - scottmcm:iter-stepby-sizehint, r=alexcrichton
Override size_hint and propagate ExactSizeIterator for iter::StepBy Generally useful, but also a prerequisite for moving a bunch of unit tests off `Range*::step_by`. A small non-breaking subset of https://github.com/rust-lang/rust/pull/42110 (which I closed). Includes two small documentation changes @ivandardi requested on that PR. r? @alexcrichton
