[SPARK-17947][SQL] Add Doc and Comment about spark.sql.debug ### What changes were proposed in this pull request? Just document the impact of `spark.sql.debug`: When enabling the debug, Spark SQL internal table properties are not filtered out; however, some related DDL commands (e.g., Analyze Table and CREATE TABLE LIKE) might not work properly. ### How was this patch tested? N/A Author: gatorsmile <gatorsm...@gmail.com> Closes #15494 from gatorsmile/addDocForSQLDebug.
