feat: add simp lemmas for kernel-friendly functions (#12950) 
This PR adds simp lemmas equating kernel-friendly function names with
their operator notation equivalents: `Nat.land_eq`, `Nat.lor_eq`,
`Nat.xor_eq`, `Nat.shiftLeft_eq'`, `Nat.shiftRight_eq'`, and
`Bool.rec_eq`. These are useful when proofs involve reflection and need
to simplify kernel-reduced terms back to operator notation.

Closes #12716
