std: Implement .rposition() on double-ended iterators with known size
This is a generalization of the vector .rposition() method, to all double-ended iterators that have the ExactSizeHint trait. This resolves the slight asymmetry around `position` and `rposition` * position from front is `vec.iter().position()` * position from the back was, `vec.rposition()` is now `vec.iter().rposition()` Additionally, other indexed sequences (only `extra::ringbuf` I think), will have the same method available once it implements ExactSizeHint.
