starocean999 86d7233b06 [fix](nereids) ExtractAndNormalizeWindowExpression rule should push down correct exprs to child (#21827)
consider the window function:
```sql
substr(
ref_1.cp_type,
sum(CASE WHEN ref_1.cp_type = 0 THEN 3 ELSE 2 END) OVER (),
1)
```
Before the pr, only "CASE WHEN ref_1.cp_type  = 0 THEN 3 ELSE 2 END" is pushed down.
But both "ref_1.cp_type" and "CASE WHEN ref_1.cp_type  = 0 THEN 3 ELSE 2 END"
should be pushed down.
This pr fix it
