  [mlir][Vector] Add vector.extract(vector.shuffle) folder (#115105)

This PR adds a folder for extracting an element from a vector shuffle.
It turns something like:

```
   %shuffle = vector.shuffle %a, %b [0, 8, 7, 15]
     : vector<8xf32>, vector<8xf32>
   %extract = vector.extract %shuffle[3] : f32 from vector<4xf32>
```

into:

```
   %extract = vector.extract %b[7] : f32 from vector<8xf32>
```
