feat(View): add stub implementation of draw_screen

The View component in MVVM handles UI layout and construction. Though it
is currently in the model directory, the `View` enum will be our View
component. Future commits will move this to it's own directory.

Add a stub implementation of a method that can draw the current
screen.
