Update `cub::DeviceTransform` vectorized path tuning

To test whether tuning works after #6914 I ran a small job for babelstream and here are some results regarding only the vectorized code path on B200:
```
cub.bench.transform.babelstream[T{ct}=I8, OffsetT{ct}=I32]:

```
Let's add those to the current tunings.
