note: this attaches `ShapedTypeInterface` but `TensorType` (base class of ranked tensor) also attaches `ShapedTypeInterface`. is there any risk that we can run into trouble due to:

```
ranked tensor type -> TensorType -> **ShapedTypeInterface**
                  |-> TensorLikeTypeInterface -> **ShapedTypeInterface**
```
