Closes #4724.
# Rationale for this change
Currently datafusion support rewrite in-subquery to join when the expression
is a column, like:
```sql
> select * from t1 where t1_id in (select t2_id from t2);
```
but following sql does not works:
```sql
> select * from t1 where t1_id + 11 in (select t2_id from t2);
NotImplemented("Physical plan does not support logical expression
CAST(t1.t1_id AS Int64) + Int64(11) IN (<subquery>)")
```
We can rewrite these subquery to join also.
