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.

`sizeof(data)` does not return the correct result here, as it measures
the size of the `data` variable, not what it points to.

Invoke the free callback for a given `Buffer` if it was created
with one, and mark the underlying `ArrayBuffer` as detached.
This makes sure that the memory is released e.g. when addons inside
Workers create such `Buffer`s.

More precisely, make them untransferable if they were created through
*our* APIs, because those do not follow the improved free callback
mechanism that V8 uses now. All other ArrayBuffers can be transferred
between threads now, the assumption being that they were created in a
clean way that follows the V8 API on this.
This addresses a TODO comment.
