      SparkSqlDialect have a unnecessary rewrite about SUBSTRING func.

      In CALCITE-3247, We handle the SUBSTRING rewrite in HiveSqlDialect.

      In CALCITE-3072, We handle the SUBSTRING rewrite in SparkSqlDialect.

      In CALCITE-5677, We refactor the SUBSTRING as the default behaviour and remove the SUBSTRING rewrite in HiveSqlDialect. This PR will remove the Spark.
