Subject: [PATCH] [Fix](Nereids) fix test leading change disable join reorder
 parameter (#23657)

Problem:
when running pipeline, we get randomly failed of test_leading
Reason:
physical distribute was generated and choosed to be the best plan because we can not get any statistic information of empty table. So we would get some unexpect result because we can not expect the order in memo
Solved:
Add statistic of columns used in test_leading, try repeatly in pipeline
