[Views] Change rasterization scale to the main screen's scale

Browse Source 
Summary:
`view.screen` can be nil if the view has not yet been added to the view hierarchy (e.g. new view), so we should use `[UIScreen mainScreen]` instead.

In the future, if we need to support multiple screens, one possible fix is to set the rasterization scale in didMoveToWindow/Superview. For now we have just one screen, though.
