Ed Page 272f840178 feat: Replace core set of AppSettings with functions
This is a part of #2717

Some settings didn't get getters because
- They are transient parse settings (e.g. ignore errors)
- They get propagated to args and should be checked there

`is_allow_hyphen_values_set` is a curious case.  In some cases, we only
check the app and not an arg.  This seems suspicious.
