[base] Revert "Move hashmap allocator to a field"

This reverts commit b42ecda533bd53ddc17f55e256236f23253382b8.

That commit introduced a allocator field to hashmap, which indirectly
added a field to Scopes, where the field, effectively storing a Zone, is
unnecessary because the Zone can be accessed in other ways.
