need `onScreenResume` action on View

[sharjeelyunus]

when user is switching screen from ViewGroup, onLoad is only called once, this is to improve the performance so that we don't reload everything everytime. But in some cases we need to call some action every time, e.g we have to force update the storage to update it on the new screen. The only work around is to make reloadView: false in ViewGroup, which comes with a lot of performance issues and bad UX. So need a new action onScreenResume which will work just like onLoad but will be called every time even if reloadView is false. This way we can only call the actions in onScreenResume which requires update on each page view.
