[fix](Nereids) fix fold constant by be return type mismatched (apache#39723)(apache#41164) (apache#41537)

cherry-pick: apache#39723 apache#41164 because later problem is intro by prev one,
so put them together
when using fold constant by be,
the return type of substring('123456',1, 3) would changed to be text,
which we want it to be 3 remove windowframe in window expression
to avoid folding constant on be
