jakevin 9a38a9677a [feature](Nereids) Eliminate outer join (#12985)
eliminate outer join if we have non-null predicate on slots of inner side of outer join.

TODO:
1. use constant viariable to handle it (we can handle more case like nullsafeEqual ......)
2. using constant folding to handle of null values, is more general and does not require writing long logical judgments
3. handle null safe equals(<=>)
