      Description

      This PR aims at porting minimal code to generate TPC-DS data from databricks/spark-sql-perf. The classes in a new class file tpcdsDatagen.scala are basically copied from the databricks/spark-sql-perf codebase.

      We frequently use TPCDS data now for benchmarks/tests, but the classes for the TPCDS schemas of datagen and benchmarks/tests are managed separately, e.g.,

      https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/TPCDSBase.scala
      https://github.com/databricks/spark-sql-perf/blob/master/src/main/scala/com/databricks/spark/sql/perf/tpcds/TPCDSTables.scala
      I think this causes some inconveniences, e.g., we need to update both files in the separate repositories if we update the TPCDS schema #32037. So, it would be useful for the Spark codebase to generate them by referring to the same schema definition.
