PS4, Line 125:  public NodeWithExprs getPlanNode(ParentPlanRelContext context) 
throws ImpalaException {
I have an immature idea, if we use calcite rule 
PROJECT_TO_LOGICAL_PROJECT_AND_WINDOW, 
https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/rel/rules/ProjectToWindowRule.java,
 maybe can simplify the logic of Implement analytic functions?

in this way, maybe we can easily implement rule for IMPALA-14115. and I think 
use this methods, we can reduce the difference between calcite
and then do not use AnalyticPlanner in calcite fe.(maybe)
