  [X86] combineX86ShufflesRecursively - replace Root node argument with opcode/valuetype/ismaskedshuffle data. NFC. (#132437)

Preparatory cleanup up patch to makes it easier for combineX86ShufflesRecursively/combineX86ShuffleChain to handle length changing shuffles up the shuffle chain than what combineX86ShuffleChainWithExtract can manage.

Instead of passing the original Root node, pass the root opcode and the current effective value type (which may have widened as we recurse through EXTRACT_SUBVECTOR/TRUNCATE nodes etc.).
