Yuanjian Li 3db3e39f11 [SPARK-28228][SQL] Change the default behavior for name conflict in nested WITH clause ... ### What changes were proposed in this pull request? This is a follow-up for #25029, in this PR we throw an AnalysisException when name conflict is detected in nested WITH clause. In this way, the config `spark.sql.legacy.ctePrecedence.enabled` should be set explicitly for the expected behavior. ### Why are the changes needed? The original change might risky to end-users, it changes behavior silently. ### Does this PR introduce any user-facing change? Yes, change the config `spark.sql.legacy.ctePrecedence.enabled` as optional. ### How was this patch tested? New UT. Closes #27454 from xuanyuanking/SPARK-28228-follow.
