[SPARK-17432][SQL] PreprocessDDL should respect case sensitivity when
checking duplicated columns
## What changes were proposed in this pull request?
In `PreprocessDDL` we will check if table columns are duplicated. However,
this checking ignores case sensitivity config(it's always case-sensitive) and
lead to different result between `HiveExternalCatalog` and `InMemoryCatalog`.
`HiveExternalCatalog` will throw exception because hive metastore is always
case-nonsensitive, and `InMemoryCatalog` is fine.
This PR fixes it.
## How was this patch tested?
a new test in DDLSuite
