We use two facilities to do predicate infer: PredicatePropagation and
PullUpPredicates. In the prvious implementation, we use a set to save
the intermediate result of PredicatePropagation. The purpose is infer
new predicate though two equal relation. However, it is the wrong way.
Because it could infer wrong predicate through outer join. For example
```sql
select a.c1
from a
left join b on a.c2 = b.c2 and a.c1 = '1'
left join c on a.c2 = c.c2 and a.c1 = '2'
inner join d on a.c3=d.c3
```
the predicates `a.c1 = '1'` and `a.c1 = '2'` should not be inferred as
filter to relation `a`.
This PR:
1. revert the change from PR #22145, commit 3c58e9ba
2. Remove the unreasonable restrict in PullupPredicate.
3. Use new Filter node rather than new otherCondition on join node to
save infer predicates
