Boxity: Don't update Boxity unless worker/wrapper follows (#21754)

A small refactoring in our Core Opt pipeline and some new functions for
transfering argument boxities from one signature to another to facilitate
`Note [Don't change boxity without worker/wrapper]`.

Fixes #21754.

Scrub various partiality involving empty lists.

Avoids some uses of `head` and `tail`, and some panics when an argument is null.

Enforce internal invariant of OrdList and fix bugs in viewCons / viewSnoc

`viewCons` used to ignore `Many` constructor completely, returning `VNothing`.
`viewSnoc` violated internal invariant of `Many` being a non-empty list.
