[SPARK-17495][SQL] Support Decimal type in Hive-hash
## What changes were proposed in this pull request?
Hive hash to support Decimal datatype. [Hive internally normalises decimals](https://github.com/apache/hive/blob/4ba713ccd85c3706d195aeef9476e6e6363f1c21/storage-api/src/java/org/apache/hadoop/hive/common/type/HiveDecimalV1.java#L307) and I have ported that logic as-is to HiveHash.
## How was this patch tested?
Added unit tests

Closes #17056 from tejasapatil/SPARK-17495_decimal.
