Function schedule

schedule(queue: NativePointerValue, work: () => void): void
Schedule the JavaScript function work on the GCD queue specified by queue. An NSAutoreleasePool is created just before calling work, and cleaned up on return.

E.g. on macOS:
```
    const { NSSound } = ObjC.classes;
    ObjC.schedule(ObjC.mainQueue, () => {
        const sound = NSSound.alloc().initWithContentsOfFile_byReference_("/Users/oleavr/.Trash/test.mp3", true).autorelease();
        sound.play();
    });
```
Parameters
- queue: NativePointerValue
  GCD queue to schedule work on.
- work: () => void
  Function to call on the specified queue.
Returns void
