### What problem does this PR solve?
logical apply shouldnot include right child's data trait, it's use to desc
the subquery, but the subquery's data trait may not keep in upper plans. This
PR fix this.
for example:
for sql `select * from t1 where t1.x = 1 or exists(select * from t2 where
t2.y = 10 and t1.y = t2.y and t1.z = t1.u);`
the outer where will become a plan filter:
LogicalFilter1(t1.x = 1 or ifnull(xx, false)
|
|-- LogicalProject2
|
|-- LogicalApply
|
|-- LogicalOlapScan
|
|-- LogicalProject2
|
|-- LogicalFitler2 (t2.y = 10 and t1.y
= t2.y and t1.z = t1.u)
LogicalApply's right child LoggicalProject2 will contains equal set: t1.z =
t1.u, but LogicalApply should not include this equal set. If logical apply
contains it, then logical apply's parent logical project2 will contains it,
then logical filter1 will contains it later. But we known that, for logical
filter 1, the EXISTS expression(exists(select * from t2 where t2.y = 10 and
t1.y = t2.y and t1.z = t1.u)) maynot be true, so logical filter 1 must
exclude equal set `t1.z = t1.u`
