src: throw DataCloneError on transfering untransferable objects

The HTML StructuredSerializeWithTransfer algorithm defines that when
an untransferable object is in the transfer list, a DataCloneError is
thrown.
An array buffer that is already transferred is also considered as
untransferable.

 Mark an object as not transferable. If `object` occurs in the transfer list of
-a [`port.postMessage()`][] call, it is ignored.
+a [`port.postMessage()`][] call, an error is thrown.
 
 In particular, this makes sense for objects that can be cloned, rather than
 transferred, and which are used by other objects on the sending side.
