Get error "ValueError: Input contains NaN" when MLP regression model is exploding numerically and when early_stopping=True

### Describe the bug

Hello,

I was doing dummy tests with a very basic MLP regressor, and I got an error I was not expecting: "ValueError Input contains NaN".

ValueError: Input contains NaN.
```

Basically, setting `early_stopping=True` will enable a model prediction and a r2_score computing on that prediction. However, when the network overflows and outputs NaN, it will crash when computing the r2_score.

Conversely, when `early_stopping=False`, it will not call that score and will gracefully raise the expected error: "Solver produced non-finite parameter weights. The input data may contain large values and need to be preprocessed."

### Steps/Code to Reproduce

```py
# code changed on 2024-07-19
from sklearn.neural_network import MLPRegressor
from sklearn.datasets import make_regression

x, y = make_regression(bias=100, random_state=0)

model = MLPRegressor(
    hidden_layer_sizes=100,
    activation="identity",
    solver="sgd",
    alpha=0.00009999999747378752,
    learning_rate="constant",
    learning_rate_init=1,
    shuffle=True,
    max_iter=200,
    early_stopping=True,
    n_iter_no_change=10,
    verbose=True
)
model.fit(x, y)
```

### Expected Results

ValueError: Input contains NaN.

### Actual Results

ValueError: Solver produced non-finite parameter weights. The input data may contain large values and need to be preprocessed.

COMMENT:
I don't think the MLP supports missing values. So this is intended behavior and out of scope. You should impute the data before feeding it into MLP in this case.
