[SPARK-17368] [SQL] Add support for value class serialization and deserialization ## What changes were proposed in this pull request? Value classes were unsupported because catalyst data types were obtained through reflection on erased types, which would resolve to a value class' wrapped type and hence lead to unavailable methods during code generation. This patch simply removes the erasure step when getting data types for catalyst. ## How was this patch tested? Additional tests in `ExpressionEncoderSuite`.
