Description
There are different behaviors of result of internal map state. For HeapMapState, #entries(), #keys(), #values(), and #iterator() would all return null. However, for RocksDBMapState, #entries() would return null, while #keys(), #values(), #iterator() would return empty iterator. UserFacingMapState would align these behaviors to empty iterator for users, therefore this should better align these internal behavior to return empty iterator instead of null.
