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.
