Description Ryosuke Niwa 2021-08-16 17:06:52 PDT 
We need a thread safe version of WeakPtr.

It's not sufficient to make CanMakeThreadSafe thread safe for WeakPtr
since the object can be destructed as we grab the value out of WeakPtr.

Add a mechanism to safely create RefPtr or CheckedPtr out of them.
