[SPARK-31997][SQL][TESTS] Drop test_udtf table when SingleSessionSuit…

…e test completed

### What changes were proposed in this pull request?
`SingleSessionSuite` not do `DROP TABLE IF EXISTS test_udtf` when test completed, then if we do mvn test `HiveThriftBinaryServerSuite`, the test case named `SPARK-11595 ADD JAR with input path having URL scheme` will FAILED because it want to re-create an exists table test_udtf.

### Why are the changes needed?
test suite shouldn't rely on their execution order

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

### How was this patch tested?
Manual test，mvn test SingleSessionSuite and HiveThriftBinaryServerSuite in order

Closes apache#28838 from LuciferYang/drop-test-table.
