Support UUID Type for MongoDB in ClickHouse

Why it matters

This feature enables accurate handling and representation of UUID data when using the MongoDB engine in ClickHouse, solving issues with incorrect or inconsistent UUID type support. It ensures data integrity and compatibility when querying MongoDB collections containing UUID fields.

How to use it

When querying MongoDB collections through ClickHouse's MongoDB engine, UUID values will now be properly recognized and handled automatically. No additional configuration is required; just use the MongoDB engine as before, and UUID columns will be correctly mapped to the UUID type in ClickHouse.
