ulysses 3ae1520185 [SPARK-33131][SQL] Fix grouping sets with having clause can not resolve qualified col name
### What changes were proposed in this pull request?

Correct the resolution of having clause.

### Why are the changes needed?

Grouping sets construct new aggregate lost the qualified name of grouping expression. Here is a example:
```
-- Works resolved by `ResolveReferences`
select c1 from values (1) as t1(c1) group by grouping sets(t1.c1) having c1 = 1

-- Works because of the extra expression c1
select c1 as c2 from values (1) as t1(c1) group by grouping sets(t1.c1) having t1.c1 = 1

-- Failed
select c1 from values (1) as t1(c1) group by grouping sets(t1.c1) having t1.c1 = 1
```

It wroks with `Aggregate` without grouping sets through `ResolveReferences`, but Grouping sets not works since the exprId has been changed.

### Does this PR introduce _any_ user-facing change?

Yes, bug fix.

### How was this patch tested?

add test.

Closes #30029 from ulysses-you/SPARK-33131.
