feat: internalization for grind order (#10562)
This PR simplifies the `grind order` module, and internalizes the order
constraints. It removes the `Offset` type class because it introduced
too much complexity. We now cover the same use cases with a simpler
approach:
- Any type that implements at least `Std.IsPreorder`
- Arbitrary ordered rings.
- `Nat` by the `Nat.ToInt` adapter.
