[SPARK-42239][SQL] Integrate MUST_AGGREGATE_CORRELATED_SCALAR_SUBQUERY

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

This is raised from https://github.com/apache/spark/pull/39543/files#r1082159637, to integrate the `MUST_AGGREGATE_CORRELATED_SCALAR_SUBQUERY` and `MUST_AGGREGATE_CORRELATED_SCALAR_SUBQUERY_OUTPUT`

### Why are the changes needed?

Logically, `MUST_AGGREGATE_CORRELATED_SCALAR_SUBQUERY` and `MUST_AGGREGATE_CORRELATED_SCALAR_SUBQUERY_OUTPUT` are exactly the same.

We should deduplicate the error classes when possible.

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

No.

### How was this patch tested?

Updated the existing UT.

Closes #39806 from itholic/MUST_AGGREGATE_CORRELATED_SCALAR_SUBQUERY1.
