feat: NoZeroNatDivisors helper class for grind (#8111) 
This PR adds the helper type class `NoZeroNatDivisors` for the
commutative ring procedure in `grind`. Core only implements it for
`Int`. It can be instantiated in Mathlib for any type `A` that
implements `NoZeroSMulDivisors Nat A`.
See `findSimp?` and `PolyDerivation` for details on how this instance
impacts the commutative ring procedure.
