Rollup merge of #85930 - mominul:array_into_iter, r=m-ou-se

Update standard library for IntoIterator implementation of arrays

This PR partially resolves issue #84513 of updating the standard library part.

I haven't found any remaining doctest examples which are using iterators over e.g. &i32 instead of just i32 in the standard library. Can anyone point me to them if there's remaining any?

Thanks!
