Allow access to interface args/methods from card

We should expose interface args/functions via their parent cards. We do this for some already, but not for others. For example, when creating a drift profile a user should be able to call:

### ModelCrd

```python
# ideal
card.create_drift_profile(...)

# current
card.interface.create_drift_profile(...)
```

### DataCard

```python
# ideal
card.split_data()

# current
card.interface.split_data(...)
```
