MacOS: Implement EventLoopExtPumpEvents and EventLoopExtRunOnDemand

Browse source 
The implementation of `pump_events` essentially works by hooking into the
`RunLoopObserver` and requesting that the app should be stopped the next time
that the `RunLoop` prepares to wait for new events.

Originally I had thought I would poke the `CFRunLoop` for the app directly and
I was originally going to implement `pump_events` based on a timeout which I'd
seen SDL doing.

I found that `[NSApp run]` wasn't actually being stopped by asking the RunLoop
to stop directly and inferred that `NSApp run` will actually catch this and
re-start the loop.

Hooking into the observer and calling `[NSApp stop]` actually seems like a
better solution that doesn't need a hacky constant timeout.

The end result is quite similar to what happens with existing apps that
call `run_return` inside an external loop and cause the loop to exit for
each iteration (that also results in the `NSApp` stopping each
iteration).
