[SPARK-49017][SQL][TESTS][FOLLOW-UP] Add testing for CreateTableAs wi…

…th parameters

### What changes were proposed in this pull request?
Addition of a test for `CreateTableAsSelect`.

### Why are the changes needed?
While looking through parameter marker support in statements it was noticed that CacheTableAsSelect actually should not work with parameter markers, but returns UNBOUND_SQL_PARAMETER. (https://issues.apache.org/jira/browse/SPARK-49398 ticket which should solve this issue). Because of this, I suggest adding additional test for `CreateTableAsSelect` to make sure all paths work as expected.

### Does this PR introduce _any_ user-facing change?
No, only tests added.

### How was this patch tested?
N/A

### Was this patch authored or co-authored using generative AI tooling?
No.

Closes apache#47886 from mihailom-db/follow-up-parameters.
