Relanding this as this was reverted.

Move the handling of Desktop notification IPCs coming in from the renderer into a helper
object DesktopNotificationHandler whose lifetype is dependent on the TabContents which
instantiates it. This object implements the WebNavigationObserver interface which enables
it to handle IPCs on the UI thread. 

The DeskopNotificationHandler object is also instantiated by the ExtensionHost object 
as it expects the desktop notification IPC's to be handled. I also changed the desktop
notification IPCs to carry the routing id as an additional parameter as the notification
handling in the browser needs the routing id.

BUG=70690
TEST=no change in functionality.
