[DAG] Fold freeze(shuffle(x,y,m)) -> shuffle(freeze(x),freeze(y),m) (#90952)
If the shuffle mask contains no undef elements, then we can move the freeze through a shuffle node.
This requires special case handling to create a new ShuffleVectorSDNode.
Includes VECTOR_SHUFFLE support for isGuaranteedNotToBeUndefOrPoison / canCreateUndefOrPoison.
