[C++] Add hash-join support for large-offset types (e.g. large_string) and dictionary encoded types to the new hash-join impl #31622

@asfimport

Description

@asfimport

The current proposal for the improved hash-join does not support using large binary types (those with 8 byte offsets) or dictionary types as key columns. We should support those.
