Rollup merge of #56802 - clarcharr:nth_back, r=alexcrichton
Add DoubleEndedIterator::nth_back As suggested by #54054. This doesn't fix that issue, as this doesn't add enough implementations to optimise that specific use case, but it adds the method and a few (relatively) trivial overrides to work as an initial implementation. It's probably going to be a lot of work adding `nth_back` implementations everywhere, and I don't have the time to include it all in this commit. But, it's a start. :)
