  [MLIR][vector] vector.deinterleave to vector.shuffle decomposition (#177897)

This PR adds a rewrite pattern for vector.deinterleave ops that rewrites
them using vector.shuffle ops. This is similar to the existing pattern
for vector.interleave and allows for supporting these ops for lowering
to targets without native deinterleave support. A transform dialect op
is also added to apply this pattern.
