chore: change BitVec.intMin/Max from abbrev to def (#5252) 
I don't think we gain anything from having them as `abbrev` here, and
the simpNF linter complains:

```
-- Init.Data.BitVec.Lemmas
#check @BitVec.toNat_intMin /- simp can prove this:
  by simp only [BitVec.toNat_twoPow]
One of the lemmas above could be a duplicate.
If that's not the case try reordering lemmas or adding @[priority].
 -/
#check @BitVec.toNat_intMax /- Left-hand side simplifies from
  (BitVec.intMax w).toNat
to
  (2 ^ w - 1 % 2 ^ w + 2 ^ (w - 1)) % 2 ^ w
using
  simp only [@BitVec.toNat_sub, @BitVec.ofNat_eq_ofNat, BitVec.toNat_ofNat, BitVec.toNat_twoPow, Nat.add_mod_mod]
Try to change the left-hand side to the simplified term!

 ```
