[SPARK-17659][SQL] Partitioned View is Not Supported By SHOW CREATE TABLE

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

`Partitioned View` is not supported by SPARK SQL. For Hive partitioned view, SHOW CREATE TABLE is unable to generate the right DDL. Thus, SHOW CREATE TABLE should not support it like the other Hive-only features. This PR is to issue an exception when detecting the view is a partitioned view.
### How was this patch tested?

Added a test case
