feat: critical pairs (non commutative case) for grind ac (#10206)
This PR adds superposition for associative (but non-commutative)
operators in `grind ac`. Examples:
```lean
example {α} (op : α → α → α) [Std.Associative op] (a b c d : α)
   : op a b = c →
     op b a = d →
     op (op c a) (op b c) = op (op a d) (op d b) := by
  grind

example {α} (a b c d : List α)
   : a ++ b = c →
     b ++ a = d →
     c ++ a ++ b ++ c = a ++ d ++ d ++ b := by
  grind only
```
