This PR implements `grind` propagators for `Nat` operators that have a simproc associated with them, but do not have any theory solver support. Examples: ```lean example (a b : Nat) : a = 3 → b = 6 → a &&& b = 2 := by grind example (a b : Nat) : a = 3 → b = 6 → a ||| b = 7 := by grind example (a b : Nat) : a = 3 → b = 6 → a ^^^ b = 5 := by grind example (a b : Nat) : a = 3 → b = 6 → a <<< b = 192 := by grind example (a b : Nat) : a = 1135 → b = 6 → a >>> b = 17 := by grind ``` Closes #11498
