  [X86] combineINSERT_SUBVECTOR - use peekThroughBitcastsAndExtracts helper to match target shuffles as well. NFC. (#209803)

We were always checking if the result of peekThroughBitcastsAndExtracts
was a target shuffle - so let the helper do it for us.

Makes it easier for future handling of faux shuffles as well.
