Remove some minor settings

Some spring cleaning to remove some unnecessary complexity so things are easier to maintain.

- Start screen: redundant with app shortcuts in Android 7.1+
- Jump to chapters: irrelevant in tablet mode and people can scroll a tiny bit if they really have to
- Option to not scroll away bottom nav: issues with fast scroll will be irrelevant with it being replaced or removed in the Compose migrations

Get ready for people malding over their special needs. https://xkcd.com/1172/
