Implements the EventWindowFocusIn and EventWindowFocusOut events on macOS.
It is worth noting that macOS has different types of focus: whether the application is active, whether a window accepts input (key window) and whether a window is the main window (has the active appearance). This implementation listens to 'key window' events, because this gives expectations consistent with the X11 and Windows implementations.
