feat: improve grind cutsat support for Fin n when n is not a numeral (#10022) 
This PR improves support for `Fin n` in `grind cutsat` when `n` is not a
numeral. For example, the following goals can now be solved
automatically:

```lean
example (p d : Nat) (n : Fin (p + 1)) 
    : 2 ≤ p → p ≤ d + 1 → d = 1 → n = 0 ∨ n = 1 ∨ n = 2 := by
  grind

example (s : Nat) (i j : Fin (s + 1)) (hn : i ≠ j) (hl : ¬i < j) : j < i := by
  grind

example {n : Nat} (j : Fin (n + 1)) : j ≤ j := by
  grind

example {n : Nat} (x y : Fin ((n + 1) + 1)) (h₂ : ¬x = y) (h : ¬x < y) : y < x := by
  grind
```
