Allow Hash Functions to Accept Map Type Arguments

Why it matters

This feature enables users to apply hash functions directly to Map data types, which previously were unsupported. It enhances the flexibility and functionality of hash operations in queries involving complex data structures.

How to use it

Users can now pass columns or expressions of type Map as arguments to hash functions without additional conversions or workarounds. Simply use the hash function as usual, for example: SELECT cityHash64(my_map_column) FROM table.
