URL: https://github.com/apache/doris/pull/32286
## Proposed changes
- fix syntax problems of only one table used in leading or mistake usage of
brace
example: leading(t1),leading(t1 {t2})
- fix cte used in subquery of using leading
example: with cte as (select c1 from t1) select count(*) from t1 join
(select /*+ leading(cte t2) */ c2 from t2 join cte on c2 = cte.c1) as alias on
t1.c1 = alias.c2;
which cte used in subquery and subquery also have leading
- fix data mismatched with original plan cause of on predicate push to
nullable side
example: select count(*) from t1 left join t2 on c1 > 500 and c2 > 500 can
not change to select count(*) from t1 left join t2 on c2 > 500 where c1 > 500
