[Merged by Bors] - feat(analysis/normed_space/basic): add normed_division_ring
#12132

This does several things: 1. Moves the division ring lemmas into root namespace 2. Deletes the corresponding lemmas from the normed field namespace 3. Deletes the `normed_field.` references across mathlib

This defines normed division rings and generalizes some of the lemmas that applied to normed fields instead to normed division rings. This breaks one `ac_refl`; although this could be resolved by using `simp only {canonize_instances := tt}` first, it's easier to just tweak the proof.
