  [MLIR][Vector] Extend elementwise pattern to support unrolling from higher rank to lower rank (#162515)

This PR enhances the elementwise unrolling pattern to support higher
rank to lower rank unroll. The approach is to add leading unit dims to
lower rank targetShape to match the rank of original vector (because
ExtractStridedSlice requires same rank to extractSlices), extract slice,
reshape to targetShape's rank and perform the operation.
