As discussed previously, this PR enables stats on spark's query plans
What changes were proposed in this pull request?
Enable stats in native spark's gold standard test cases. The stats are picked directly from apache spark 3.0+ codebase from this file https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/TPCDSTableStats.scala
This ensures that for joining large tables, Broadcast join is replaced by SortMergeJoin.
