The concrete types of `[Global]` DOM interfaces have `origin` methods,
which were used before this commit. Some of them just delegate to
`GlobalScope::origin` while others are implemented differently. This
commit changes the created principals objects' associated origins in the
following way:
- `DedicatedWorkerGlobalScope` - was `WorkerGlobalScope::worker_url`
- `DissimilarOriginWindow` - no change
- `PaintWorkletGlobalScope` - no change
- `ServiceWorkerGlobalScope` - was `ServiceWorkerGlobalScope::scope_url`
- `TestWorkletGlobalScope` - no change
- `Window` - no change
