  [mlir] Reuse pack dest in tensor.pack decomposition (#108025)

In the `lowerPack` transform, there is a special case for lowering into
a simple `tensor.pad` + `tensor.insert_slice`, but the destination
becomes a newly created `tensor.empty`. This PR fixes the transform to
reuse the original destination of the `tensor.pack`.
