[TIMOB-26700] Windows: Optimize UI rendering calls

   Ti.Analytics.optedOut = true; // Just to make sure networking won't affect the test
   
   var win = Ti.UI.createWindow({ backgroundColor: 'green' });
   
   win.addEventListener('open', function () {
       var start = +new Date();
       for (var i = 0; i < 200; i++) {
           win.add(Ti.UI.createLabel({
               width: 200, height: 50, left: i * 10, top: i * 10, backgroundColor: '#0000FF', text: 'Hello, World'
           }));
       }
   
       // setTimeout() effectively push tasks on UI thread.
       // This can be useful when you need to see actual UI response time.
       setTimeout(function () {
           alert((+new Date() - start) + ' m seconds elapsed');
       }, 0)
   });
   
   win.open();
