Since we have a delegate API for service worker window, I re-implement `OpenWindow` for GeckoView, not use `createContentWindow.createContenttWindow` doesn't use service worker delegation. Current implementation doesn't set `nsIOpenWindowInfo`` to create new window. But we should attach it to set `OriginAttributes`, then we have to wait for ready of browsing context.
