  [VectorUtils] Add llvm::scaleShuffleMaskElts wrapper for narrowShuffleMaskElts/widenShuffleMaskElts, NFC. (#96646)

Using the target number of vector elements, scaleShuffleMaskElts will try to use narrowShuffleMaskElts/widenShuffleMaskElts to scale the shuffle mask accordingly.

Working on #58895 I didn't want to create yet another case where we have to handle both re-scaling cases.
