Inconsistency in AUC ROC and AUPR API

### Describe the bug

When only one class is present on the groundtruth. The function `roc_auc_score` throws an `ValueError` and exits while the `average_precision_score` returns `-0.0`. I feel that both functions should return similar output in this case.

### Steps/Code to Reproduce

```python
from sklearn.metrics import roc_auc_score,  average_precision_score

y_true = [1]*10
prob = [0.49]*10

auc_roc = roc_auc_score(y_true, prob)
aupr= average_precision_score(y_true, prob)

```

### Expected Results

auc_roc = roc_auc_score(y_true, prob) >> throws `ValueError: Only one class present in y_true. ROC AUC score is not defined in that case`

aupr=-0.0

### Actual Results

Both should have similar outputs

COMMENT:
So I would not consider it a bug since there are no real "wrong" results.
We could improve the consistency since that now:

- Calling `roc_curve` and `ROCCurveDisplay` will not raise an error but a warning
- `roc_auc_score` will raise an error
- `precision_recall_curve`, `average_precision_score` and display will raise a warning.

Maybe having `roc_auc_score` raising a warning and having the same behaviour as the curve would be OK.
