Auto merge of #87974 - steffahn:slice_split_size_hints, r=dtolnay
Test and fix `size_hint` for slice’s [r]split* iterators Adds extensive test (of `size_hint`) for all the _[r]split*_ iterators. Fixes `size_hint` upper bound for _split_inclusive*_ iterators which was one higher than necessary for non-empty slices. Fixes `size_hint` lower bound for _[r]splitn*_ iterators when _n == 0_, which was one too high. **Lower bound being one too high was a logic error, violating the correctness condition of `size_hint`.** _Edit:_ I’ve opened an issue for that bug, so this PR fixes #87978
