chore: Split Data.{Nat,Int}{.Order}.Basic in group vs ring instances (#11924)

Scatter the content of Data.Nat.Basic across:

Data.Nat.Defs for the lemmas having no dependencies
Algebra.Group.Nat for the monoid instances and the few miscellaneous lemmas needing them.
Algebra.Ring.Nat for the semiring instance and the few miscellaneous lemmas following it.

Similarly, scatter

Data.Int.Basic across Data.Int.Defs, Algebra.Group.Int, Algebra.Ring.Int
Data.Nat.Order.Basic across Data.Nat.Defs, Algebra.Order.Group.Nat, Algebra.Order.Ring.Nat
Data.Int.Order.Basic across Data.Int.Defs, Algebra.Order.Group.Int, Algebra.Order.Ring.Int

Also move a few lemmas from Data.Nat.Order.Lemmas to Data.Nat.Defs.

 # Lemma about the coercion `ℕ → WithBot ℕ`.

ee0c179c

chore: remove legacy termination_by' (#5426)

This adds a couple of WellFoundedRelation instances, like for example WellFoundedRelation (WithBot Nat). Longer-term, we should probably add a WellFoundedOrder class for types with a well-founded less-than relation and a [WellFoundOrder α] : WellFoundedRelation α instance (or maybe just [LT α] [IsWellFounded fun a b : α => a < b] : WellFoundedRelation α).
