MangaScreen: Ditch the expanded app bar (#7470)

Animating the content padding that's used for the lazy list is heavy. A simple
fix to *just* offset the list is blocked by a Compose fling issue (b/179417109).

So I decided to go with the previous layout of this screen by putting everything
in the list. MangaInfoHeader is split into separate composables to avoid jank
when the item is being inflated.
