  -----------
  [mlir][VectorOps] Add fold vector.shuffle -> vector.interleave (#80968)

This folds fixed-size vector.shuffle ops that perform a 1-D interleave
to a vector.interleave operation.

For example:

```mlir
%0 = vector.shuffle %a, %b [0, 2, 1, 4] : vector<2xi32>, vector<2xi32>
```

folds to:

```mlir
%0 = vector.interleave %a, %b : vector<2xi32>
```

Depends on: #80967
