Called when an extension needs a browser to host a background script specified via the "background" manifest key.
The browser will have no visible window and cannot be displayed. To allow creation of the browser optionally

ILifeSpanHandler.OnAfterCreated, and IBrowserHost.IsBackgroundHost
will return true for the resulting browser. See https://developer.chrome.com/extensions/event_pages for more information
