[SPARK-36339][SQL] References to grouping that not part of aggregation should be replaced

### What changes were proposed in this pull request?

Currently, references to grouping sets are reported as errors after aggregated expressions, e.g.
```
SELECT count(name) c, name
FROM VALUES ('Alice'), ('Bob') people(name)
GROUP BY name GROUPING SETS(name);
```
Error in query: expression 'people.`name`' is neither present in the group by, nor is it an aggregate function. Add to group by or wrap in first() (or first_value) if you don't care which value you get.;;

### Why are the changes needed?

Fix the map anonymous function in the constructAggregateExprs function does not use underscores to avoid

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Unit tests.

Closes #33574 from gaoyajun02/SPARK-36339.
