Re-add the wrapper class id to AsyncWrap instances so they can be tracked directly in a heapdump. Previously the class id was given without setting the heap dump wrapper class info provider. Causing a segfault when a heapdump was taken. This has been added, and the label_ set to the given provider name so each instance can be identified. The id will not be set of the passed object has no internal field count. As the class pointer cannot be retrieved from the object. In order to properly report the allocated size of each class, the new pure virtual method self_size() has been introduces.
