[X86][SSE] Replace foldShuffleOfHorizOp with generalized version in canonicalizeShuffleMaskWithHorizOp

foldShuffleOfHorizOp only handled basic shufps(hop(x,y),hop(z,w)) folds - by moving this to canonicalizeShuffleMaskWithHorizOp we can work with more general/combined v4x32 shuffles masks, float/integer domains and support shuffle-of-packs as well.

The next step will be to support 256/512-bit vector cases.
