Auto merge of #77594 - timvermeulen:chain_advance_by, r=scottmcm
Implement advance_by, advance_back_by for iter::Chain Part of #77404. This PR does two things: - implement `Chain::advance[_back]_by` in terms of `advance[_back]_by` on `self.a` and `advance[_back]_by` on `self.b` - change `Chain::nth[_back]` to use `advance[_back]_by` on `self.a` and `nth[_back]` on `self.b` This ensures that `Chain::nth` can take advantage of an efficient `nth` implementation on the second iterator, in case it doesn't implement `advance_by`. cc `@scottmcm` in case you want to review this
