We now create a WorkerAgent for the parent context, which is currently only a Window. Note that Workers can have Workers per the spec. The WorkerAgent spawns a WebWorker process to hold the actual script execution of the Worker. This is modeled with the DedicatedWorkerHost object in the WebWorker process. A start_dedicated_worker IPC method in the WebWorker IPC creates the WorkerHost object. Future different worker types may use different IPC messages to create their WorkerHost instance. This implementation cannot yet postMessage between the parent and the child processes. Co-Authored-By: Andreas Kling <kling@serenityos.org>
