[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?
