script: Allow to throw a custom exception on structured cloning (#37948)

Browse source 
The structured cloning with transfer list
https://html.spec.whatwg.org/multipage/#structuredserializewithtransfer
throws a "DataCloneError" DOM expection by default if
serialization/transferral
is not possible, but a platform object can throw a custom excepton on
its serialization/transfer steps.

One example is OffscreenCanvas, which can throw
an "InvalidStateError" exception if the context mode is not none on
transfer steps.

Testing: Improvements in the following tests
