Support recursive planning of recurring inner joins when there is a reference to outer query

Currently, Citus can successfully execute queries with recurring left join with a reference to outer query via recursive planning. However, when the same subquery uses an INNER JOIN, recursive planning is not applied, and the query fails during planning.

```
Q1: Fails
SELECT COUNT(*) FROM dist_1 t1
WHERE NOT EXISTS (
SELECT * FROM ref_1 t3
JOIN dist_1 t2 USING (a)
WHERE t3.a = t1.a
);
ERROR: complex joins are only supported when all distributed tables are co-located and joined on their distribution columns

Q2: Works
SELECT COUNT(*) FROM dist_1 t1
WHERE NOT EXISTS (
SELECT * FROM ref_1 t3
LEFT JOIN dist_1 t2 USING (a)
WHERE t3.a = t1.a
);
```
