> SPARK-28057 adds {{forceCopy}} to private {{mapChildren}} method in {{TreeNode}} to realize the {{clone()}} method.
> After SPARK-34989, the call corresponding to {{forceCopy=false}} is changed to use {{{}withNewChildren{}}}, and {{forceCopy}} always true and the private {{mapChildren}} only used by {{clone()}} method.
