This PR upstreams lemmas about `Rat` from `Mathlib.Data.Rat.Defs` and `Mathlib.Algebra.Order.Ring.Unbundled.Rat`, specifically enough to get `Lean.Grind.Field Rat` and `Lean.Grind.OrderedRing Rat`. In addition to the lemmas, instances for `Inv Rat`, `Pow Rat Nat` and `Pow Rat Int` have been upstreamed. --------- Co-authored-by: Kim Morrison <kim@tqft.net>
