[X86] combineX86ShufflesRecursively - split the getTargetShuffleInputs call from the resolveTargetShuffleAndZeroables call.

Exposes an issue in getFauxShuffleMask where the OR(SHUFFLE,SHUFFLE) decode should always resolve zero/undef elements.

Part of the fix for PR43024 where ideally we shouldn't call resolveTargetShuffleAndZeroables for Depth == 0
