) Do same job with pr #32758 and pr #33843. Because the master branch2.0 differ in binding order by expressions. So this pr is not a cherry-pick, but actually does same job. For each order by expression: If it does not have aggregate functions, firstly bind expression from aggregate outputs. If not found, then bind expression from aggregate child outputs. If it has aggregate functions, firstly bind expression from aggregate outputs which do not have aggregate functions. If not found, then bind expression from aggregate child outputs.

select sum(a) c1, min(a) c1 from t1 group by b order by c1;
This pr make the bind logic in order by list same with mysql. Doris used to report error in this situation, but mysql bind to the first c1.
When there are more than one c1 in agg outputs, the c1 in order by should bind to the first c1 in projection.
