  [mlir][VectorOps] Support vector transfer_read/write unrolling for memrefs with vector element type.

Summary:
[mlir][VectorOps] Support vector transfer_read/write unrolling for memrefs with vector element type.  When unrolling vector transfer read/write on memrefs with vector element type, the indices used to index the memref argument must be updated to reflect the unrolled operation.   However, in the case of memrefs with vector element type, we need to be careful to only update the relevant memref indices.

For example, a vector transfer read with the following source/result types, memref<6x2x1xvector<2x4xf32>>, vector<2x1x2x4xf32>, should only update memref indices 1 and 2 during unrolling.
