feat: improve support for Field in grind (#8786) 
This PR improves the support for fields in `grind`. New supported
examples:
```lean
example [Field α] [IsCharP α 0] (x : α) : x ≠ 0 → (4 / x)⁻¹ * ((3 * x^3) / x)^2 * ((1 / (2 * x))⁻¹)^3 = 18 * x^8 := by grind
example [Field α] (a : α) : 2 * a ≠ 0 → 1 / a + 1 / (2 * a) = 3 / (2 * a) := by grind
example [Field α] [IsCharP α 0] (a : α) : 1 / a + 1 / (2 * a) = 3 / (2 * a) := by grind
example [Field α] [IsCharP α 0] (a b : α) : 2*b - a = a + b → 1 / a + 1 / (2 * a) = 3 / b := by grind
example [Field α] [NoNatZeroDivisors α] (a : α) : 1 / a + 1 / (2 * a) = 3 / (2 * a) := by grind
example [Field α] {x y z w : α} : x / y = z / w → y ≠ 0 → w ≠ 0 → x * w = z * y := by grind
example [Field α] (a : α) : a = 0 → a ≠ 1 := by grind
example [Field α] (a : α) : a = 0 → a ≠ 1 - a := by grind
