  [mlir][vector] Fix vector.broadcast lowering for scalable vectors (#66344)

This patch makes sure that the following case is lowered correctly
("duplication"):
```
  func.func @broadcast_scalable_duplication(%arg0: vector<[32]xf32>) -> vector<1x[32]xf32> {
    %res = vector.broadcast %arg0 : vector<[32]xf32> to vector<1x[32]xf32>
    return %res : vector<1x[32]xf32>
  }
```
