Only create one Browser->NS factory bundle per-frame for routing the subresource requests. Prefetch, Topics, and KeepAlive will share the same channels. Offline testing shows that this improves the Memory.Browser.PrivateMemoryFootprint by 40KB per-frame if Topics is enabled, and by 80KB per-frame if both Topics and the new KeepAlive architecture is enabled.
