LogisticRegressionCV does not handle sample weights as expected when using liblinear solver

Note: this is a special case of a the wider problem described in:

- https://github.com/scikit-learn/scikit-learn/issues/15657


### Describe the bug

`_log_reg_scoring_path` used within `LogisticRegressionCV` with `liblinear` solver not returning the same coefficients when weighting samples using `sample_weight` versus when repeating samples based on weights.

NOTE: L801 in `_log_reg_scoring_path` does not pass `sample_weight` into scorer when scorer is not specified, needs fixing.

### Steps/Code to Reproduce

```python
import numpy as np
from sklearn.datasets import make_classification
from sklearn.metrics import get_scorer
from sklearn.linear_model import LogisticRegression, LogisticRegressionCV
from sklearn.model_selection import LeaveOneGroupOut


import sklearn
sklearn.set_config(enable_metadata_routing=True)

rng = np.random.RandomState(0)

X, y = make_classification(
        n_samples=300000, n_features=8,
            random_state=10,
            n_informative=4,
            n_classes=2,

)
        

n_samples = X.shape[0] // 3
sw = np.ones_like(y)

# We weight the first fold n times more.
sw[:n_samples] = rng.randint(0, 5, size=n_samples)
groups_sw = np.r_[
    np.full(n_samples, 0), np.full(n_samples, 1), np.full(n_samples, 2)
]
splits_weighted = list(LeaveOneGroupOut().split(X, groups=groups_sw))

# We repeat the first fold n times and provide splits ourselves and overwrite
## initial resampled data
X_resampled_by_weights = np.repeat(X, sw.astype(int), axis=0)

##Need to know number of repitions made in total
n_reps = X_resampled_by_weights.shape[0] - X.shape[0]

y_resampled_by_weights = np.repeat(y, sw.astype(int), axis=0)
groups = np.r_[
    np.full(n_reps + n_samples, 0), np.full(n_samples, 1), np.full(n_samples, 2)
]
splits_repeated = list(LeaveOneGroupOut().split(X_resampled_by_weights, groups=groups))

est_weighted = LogisticRegression(solver = "liblinear").fit(X,y,sample_weight=sw)
est_repeated = LogisticRegression(solver = "liblinear").fit(X_resampled_by_weights,y_resampled_by_weights)

np.testing.assert_allclose(est_weighted.coef_, est_repeated.coef_)


est_weighted = LogisticRegressionCV(cv=splits_weighted, solver = "liblinear").fit(X,y,sample_weight=sw)

est_repeated = LogisticRegressionCV(cv=splits_repeated, solver = "liblinear").fit(X_resampled_by_weights,y_resampled_by_weights)

np.testing.assert_allclose(est_weighted.coef_, est_repeated.coef_)
```

COMMENT:
Thanks for the report.

I agree that the reproducer makes sense: the repeated samples in the within the first CV group should be equivalent to weighting the samples within this same first CV group.
