Emulate TrackingVH using WeakVH

Summary:
This frees up one slot in the HandleBaseKind enum, which I will use
later to add a new kind of value handle.  The size of the
HandleBaseKind enum is important because we store a HandleBaseKind in
the low two bits of a (in the worst case) 4 byte aligned pointer.
