Implement fast and slow value object hash paths

- Use the recursive fast path for value object hash
  computation.
- Use the fast path while the recursion depth is
  below J9_VALUE_TYPE_HASH_DEPTH_LIMIT.
- Switch to the iterative path when the recursion
  depth limit is exceeded.
- Use a DFS-based queue to traverse value object
  fields in the iterative path.
- Add -XX:hashMaxRecDepth debug option to override
  default recursion depth.
