Convert the Regular VStacks / HStacks into Lazy Versions

[saiankit]

By default, SwiftUI’s VStack and HStack load all their contents upfront, which is likely to be slow if you use them inside a scroll view.
If you want to load content lazily – i.e., only when it scrolls into view, you should use LazyVStack and LazyHStack as appropriate.
