Bug 1996014 [wpt PR 55619] - [OriginAPI] Delegate origin extraction for ExtendableMessageEvent., a=testonly

Automatic update from web-platform-tests
[OriginAPI] Delegate origin extraction for `ExtendableMessageEvent`.

We can't directly work with an `ExtendableMessageEvent` from within
`DOMOrigin::from()`, as the former is defined in //modules, while the
latter is defined in //core. This CL teaches `Event` (the first ancestor
in `ExtendableMessageEvent`'s prototype chain) to support origin
extraction, and overrides its default no-op implementation in both
`MessageEvent` and `ExtendableMessageEvent`.
