[SPARK-14684] [SQL] Verification of Partition Specs in SessionCatalog
#### What changes were proposed in this pull request?
When users inputting invalid partition spec, we might not be able to catch
and issue the error messages. Sometimes, it could cause a disaster result. For
example, before the PR, when we alter a table and drop a partition with using
unknown partitioning columns, we drop all the partitions due to a bug/defect in
Hive Metastore API.
This PR is to add all the partition-related verification in
`SessionCatalog`.
#### How was this patch tested?
Fixed the illegal existing test cases and added new test cases.
