  [APInt] byteSwap - handle any whole byte bitwidth greater than 16-bits

As noted on D74621, the bswap intrinsic has a self imposed limitation that the type's bitwidth must be divisible by 16, but there's no reason that APInt::byteSwap must have the same limitation, given that it can already handle any byte width.
