feat: add Bitvec.[(toInt, toFin)_twoPow, toNat_twoPow_of_le, toNat_twoPow_of_lt, toNat_twoPow_eq_ite] (#7225)
This PR contains `BitVec.(toInt, toFin)_twoPow` theorems, completing the
API for `BitVec.*_twoPow`. It also expands the `toNat_twoPow` API with
`toNat_twoPow_of_le`, `toNat_twoPow_of_lt`, as well as
`toNat_twoPow_eq_if` and moves `msb_twoPow` up, as it is used in the
`toInt_msb` proof.
