  [InstCombine] Refactor fixed and scalable binop shuffle combine. NFCI (#141287)

This extracts the logic that works out the "unshuffled" constant when
pulling shuffle vectors out of binary ops, so the same combine can be
generic over fixed and scalable vectors.

The plan is to reuse this helper to do the same canonicalization on
intrinsics too.
