macOS: Shim all malloc zones.

All information about malloc zones [and their original functions] is stored in
MallocZoneAggregator. When the allocator shim is ready to dispatch back to the
original system implementations, it calls the MallocZoneAggregator with
|context|, which provides enough information to dispatch to the correct malloc
zone.
