src: distinguish HTML transferable and cloneable
The HTML structured serialize algorithm treats transferable and
serializable as two different bits. A web platform interface can be
both transferable and serializable.

Splits BaseObject::TransferMode to be able to compose the two bits
and distinguishes the transferable and cloneable.
