Title: [SPARK-4272] [SQL] Add more unwrapper functions for primitive type in TableReader

Currently, the data "unwrap" only support couple of primitive types, not all, it will not cause exception, but may get some performance in table scanning for the type like binary, date, timestamp, decimal etc.
