[Fix](nereids) fix condition function partition prune (apache#39298)

Current partition prune logic cannot correctly deal with condition
function in predicates. For example, where if(substring('abc',1,2) <>
"case", a > 0, b > 0), if the first parameter is not fold by
FoldConstantRule, then our current logic will also intersect the
partition range of b with b>0. If one of the partitions is empty, the
partition will be trimmed. However, substring('abc',1,2) <> "case" is
true, the predicate b>0 is not useful and should not be involved in
partition trimming.
This pr remove the logic that make the result to "Boolean.False" when
considering the child ranges and finding an empty range.
