Create a managed pointer having a target object referenced by the specified `ptr`, owning the managed object `*ptr`, and having a deleter that will invoke the specified `deleter` with the address of the currently managed object, and with the specified `cookie` (that the deleter can use for its own purposes), unless `0 == ptr`, in which case create an empty managed pointer. This constructor will not compile unless `MANAGED_TYPE *` is convertible to `TARGET_TYPE *`. The deleter will invoke the destructor of `MANAGED_TYPE` rather than the destructor of `TARGET_TYPE`. The behavior is undefined if `ptr` is already managed by another object, or if `0 == deleter && 0 != ptr`.
