REGRESSION (Safari 26): Crash in WebProcess due to checkTopOrigin called from
WebSWServerConnection::registerServiceWorkerClient with blob urls

Reviewed by Brady Eidson.
The UIProcess is responsible to notify the network process whether a given web
process can access cookies for a given top origin.
This logic is used when doing navigation, for instance in
WebProcessPool::processForNavigation.
The principle is to get a Site from a request URL and allow the origin.
But the computation of RegistrableDomain for a blob URL was leading to
nullOrigin.
This would lead WebProcessPool::processForNavigation to register nullOrigin
instead of the actual origin of the blob URL.
This woudl then trigger termination of the web process loading the blob page.
We fix the blob URL logic and add an API test to verify that computation is
correct.
