AK: Remove HashMap::hash()

Browse Source 
Using `pair_int_hash()` which subsequently uses `int_hash()` means that
ordering of the input is important. Since this operates on unordered
HashMaps as well, order of the keys and values is dependent on the
internal implementation of HashTable and might differ between HashMaps
with identical contents, making this implementation of `::hash()` not
that useful.

Fortunately, it is unused, so let's remove this footgun.
