Revert "core: set PROVIDER type as Persistent class id"
This reverts commit
3c44100558b4e9e48e0e711e38acc91e0f870a9f.
Reverted for breaking node-heapdump[0].
AsyncWrap assigns a class id but does not set a v8::RetainedObjectInfo
provider callback with v8::HeapProfiler::SetWrapperClassInfoProvider().
The result is a null pointer dereference when taking a heap snapshot.
It can probably be solved by setting a generic provider callback inside
the AsyncWrap constructor but that may have performance ramifications
that need to be investigated first. I move to revert it for now.
