This commit provides IPC endpoint to WebWorker processes that allows new WebWorker processes to be requested (just like what WebContent has). This is implemented by proxying the request_worker_agent call from WebWorker through WebContent to LibWebView. This allows the WPT test... http://wpt.live/referrer-policy/gen/worker-classic.http-rp/unsafe-url/worker-classic.http.html ...to pass, and the same is likely true for similar tests.
