Feature : Shift to ViewBinding

**Is your feature request related to a problem? Please describe.**

Kotlin Synthetic is deprecated .

**Describe the solution you'd like**

The app uses kotlin synthetics at a number of places but it's now deprecated by google. Kotlin doesn't support synthetic so a new approach has been provided by google i.e using the view binding or data binding. View binding is comparatively lighter for rendering UIs as compared to the data binding. So we can use view binding instead of kotlin synthetics. ( Thanks @abhinav78910)
