Add nullability annotations to several Collection types.

N.B. List has already been annotated (see List.annotated.java) and
most of these annotations are just copies of those. There are
additional methods on Queue and Deque, where the only interesting
thing is the distinction between peek vs element, poll vs remove, etc.
