Title: core::iter::order functions now take two types of iterators.

Closes #14278.

Previously the type signatures of the ordering functions in `core::iter::order` took two iterators, but only if they were the same type of iterator. This commit loosens that restriction and allows different kinds of iterators (but with the same type of elements) to be compared.
