  [mlir][vector] Extend `CreateMaskFolder` (#75842)

Extends `CreateMaskFolder` pattern so that the following:
```mlir
  %c8 = arith.constant 8 : index
  %c16 = arith.constant 16 : index
  %0 = vector.vscale
  %1 = arith.muli %0, %c16 : index
  %10 = vector.create_mask %c8, %1 : vector<8x[16]xi1>
```

is folded as:

```mlir
  %0 = vector.constant_mask [8, 16] : vector<8x[16]xi1>
```
