Subject: [SPARK-15232][SQL] Add subquery SQL building tests to
 LogicalPlanToSQLSuite

## What changes were proposed in this pull request?

We currently test subquery SQL building using the `HiveCompatibilitySuite`. The is not desired since SQL building is actually a part of `sql/core` and because we are slowly reducing our dependency on Hive. This PR adds the same tests from the whitelist of `HiveCompatibilitySuite` into `LogicalPlanToSQLSuite`.

## How was this patch tested?

This adds more testcases. Pass the Jenkins tests.

Closes #14383 from dongjoon-hyun/SPARK-15232.
