edc22c64 - [X86] getFauxShuffleMask - only handle VTRUNC nodes with matching src/dst sizes (#134161)

[X86] getFauxShuffleMask - only handle VTRUNC nodes with matching src/dst sizes (#134161) Cleanup work for #133947 - we need to handle VTRUNC nodes with large source vectors directly to allow us to widen the size of the shuffle combine We currently discard these results in combineX86ShufflesRecursively anyhow as we don't allow inputs from getTargetShuffleInputs to be larger than the shuffle value type
