Function schedule

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();
    });
