WinRT: move most of GUI event dispatcher logic into core

The native event dispatcher is responsible for delivering callbacks
to non-GUI handlers, such as network socket listeners. So, the non-GUI
logic is moved into the core dispatcher so that the event loop works
better for apps (and test cases) which use QCoreApplication.
