  [mlir][Vector] Fix `vector.shuffle` folder for poison indices (#124863)

This PR fixes the folder of a `vector.shuffle` with constant input
vectors in the presence of a poison index. Partially poison vectors are
currently not supported in UB so the folder select v1[0] for elements
indexed by poison.
