// PlzServiceWorker:
// Fetches the service worker's main script and creates
// blink::mojom::WorkerMainScriptLoadParams to start a worker.
//
// This is used only when the worker is newly installed and the byte-for-byte
// update checking is not invoked. The worker script needs to be loaded on the
// browser process before selecting a process for the worker thread because we
// need to know whether the worker thread needs to be in the COOP-COEP protected
// process or not.
//
// Internally, this class creates ServiceWorkerNewScriptLoader to start loading
// the script. After receiving the response header and the Mojo data pipe for
// the body, the Mojo endpoints owned by this instance gets unbound and passed
// to the struct blink::mojom::WorkerMainScriptLoadParams along with the
// response header and the Mojo data pipe so that the renderer takes over
// ownership of ServiceWorkerNewScriptLoader.
