fix: replace unary Nat.succ simp rules with simprocs (#3808) 
This removes simp attributes from `Nat.succ.injEq` and
`Nat.succ_sub_succ_eq_sub` to replace them with simprocs. This is
because any reductions involving `Nat.succ` has a high risk of leading
proof performance problems when dealing with even moderately large
numbers.

Here are a couple examples that will both report a maximum recursion
depth error currently. These examples are fixed by this PR.

```
example : (123456: Nat) = 12345667 := by
  simp

example (x : Nat) (p : x = 0) : 1000 - (x + 1000) = 0 := by
  simp
```
