Allow hash functions for Array of Tuples in ClickHouse

Why it matters

This feature enables users to apply hash functions directly to complex data types such as arrays of tuples, which were previously unsupported. This enhances data processing capabilities and flexibility, especially when working with nested or composite data structures.

How to use it

Users can now pass arguments of type Array(Tuple(..)) to hash functions in their queries as usual, without needing to transform or flatten the data beforehand.
