[CARBONDATA-692]Supporting scalar subquery in carbon
Scalar subqueries like below not working in carbon.
```
select sum(salary) from scalarsubquery t1
where ID < (select sum(ID) from scalarsubquery t2 where t1.name = t2.name
```
Spark optimizes the subquery separately and it throws error if it find
decoder in it. So now this PR fixes to avoid optimizing the separately and only
optimize whole query once
