Added support for subqueries in parameterized views in ClickHouse.
Why it matters
This feature solves the limitation of parameterized views not supporting subqueries, enabling users to create more flexible and dynamic views that can reference complex queries as parameters.How to use it
Users can now define parameterized views that include subqueries by specifying the subquery within the parameterized view definition as usual. The system will correctly handle and execute these subqueries within the context of the parameterized view.
