[ASan] Implement malloc zone enumeration for Darwin.
Needs RevisionPublic

Details

Summary

The implementation supports both in-process and out-of-process
enumeration.

The implementation relies on the ForEachChunk() method of
the allocators and the LsanMetadataRemoteView class to enumerate
live allocations.

The implementation is only for ASan right now but should be easy to
port to LSan in the future.
