(#15971)
e31913faca is described below
commit e31913faca12206b5cbaf914b815e1a8b10cb275
Author: zhengshiJ <[email protected]>

[Feature](Nereids) Support order and limit in subquery (#15971)
1.Compatible with the old optimizer, the sort and limit in the subquery
will not take effect, just delete it directly.
```
select * from sub_query_correlated_subquery1 where
sub_query_correlated_subquery1.k1 > (select
sum(sub_query_correlated_subquery3.k3) a from sub_query_correlated_subquery3
where sub_query_correlated_subquery3.v2 = sub_query_correlated_subquery1.k2
order by a limit 1);
```
2.Adjust the unnesting position of the subquery to ensure that the conjunct
in the filter has been optimized, and then unnesting
Support:
```
SELECT DISTINCT k1 FROM sub_query_correlated_subquery1 i1 WHERE ((SELECT
count(*) FROM sub_query_correlated_subquery1 WHERE ((k1 = i1.k1) AND (k2 = 2))
or ((k1 = i1.k1) AND (k2 = 1)) ) > 0);
```
The reason why the above can be supported is that conjunction will be
performed, which can be converted into the following
```
SELECT DISTINCT k1 FROM sub_query_correlated_subquery1 i1 WHERE ((SELECT
count(*) FROM sub_query_correlated_subquery1 WHERE ((k1 = i1.k1) AND (k2 = 2 or
k2 = 1)) ) > 0);
```
Not Support:
```
SELECT DISTINCT k1 FROM sub_query_correlated_subquery1 i1 WHERE ((SELECT
count(*) FROM sub_query_correlated_subquery1 WHERE ((k1 = i1.k1) AND (k2 = 2))
or ((k2 = i1.k1) AND (k2 = 1)) ) > 0);
```
