AK: Implement {any,all}_of(IterableContainer&&, Predicate)

This is a generally nicer-to-use version of the existing {any,all}_of()
that doesn't require the user to explicitly provide two iterators.
As a bonus, it also allows arbitrary iterators (as opposed to the hard
requirement of providing SimpleIterators in the iterator version).
