[X86] combineX86ShuffleChainWithExtract - don't both widening inputs after peeking through ISD::EXTRACT_SUBVECTOR nodes

combineX86ShuffleChain no longer has to assume that the shuffle inputs are the right size, so don't create unnecessary nodes messing up oneuse limits as detailed on Issue #45319

Removing widening from combineX86ShufflesRecursively will be the next step, followed by removing combineX86ShuffleChainWithExtract entirely
