src: avoid making JSTransferable wrapper object weak

JSTransferable wrapper object is a short-lived wrapper in the scope of
the serialization or the deserialization. Make the JSTransferable
wrapper object pointer as a strongly-referenced detached BaseObjectPtr
so that a JSTransferable wrapper object and its target object will never
be garbage-collected during a ser-des process, and the wrapper object
will be immediately destroyed when the process is completed.
