[SPARK-19235][SQL][TEST][FOLLOW-UP] Enable Test Cases in DDLSuite with Hive Metastore

### What changes were proposed in this pull request?
This is a follow-up of enabling test cases in DDLSuite with Hive Metastore. It consists of the following remaining tasks:
- Run all the `alter table` and `drop table` DDL tests against data source tables when using Hive metastore.
- Do not run any `alter table` and `drop table` DDL test against Hive serde tables when using InMemoryCatalog.
- Reenable `alter table: set serde partition` and `alter table: set serde` tests for Hive serde tables.
