SVC and OneClassSVM fails to fit or have wrong fitted attributes with null sample weights

### Describe the bug

*SVC().fit(X, y, w)* fails when the targets *y* are multiclass and the sample_weights *w* zero out one of the classes.
* Dense *X* produces incorrect arrays for *support_*, *n_support_*, and *dual_coef_* attributes, some with wrong dimension.
* Sparse *X* errors out when trying to construct sparse *dual_coef_* from incompatible arguments.

A warning is emitted (*e.g.*, "class label 0 specified in weight is not found"), but it does not indicate that the arrays on the trained SVC object are incorrect.

Seems to be a case that was not tested by PR #14286.

### Workaround

Replace the zero weights (or negative weights) with very small values like 1e-16. 

### Steps/Code to Reproduce

```python
import numpy as np
from sklearn.svm import SVC

X = np.array([[0., 0.], [1., 0.], [0., 1.]])   # or sp.csr_matrix(...)
y = [0, 1, 2]
w = [0., 1., 1.]                               # class 0 has zero weight
clf = SVC().fit(X, y, w)
```

### Expected Results

The fitted attributes should be
```
classes_: [0 1 2]
support_: [1 2]
support_vectors_: [[1. 0.]
                   [0. 1.]]
n_support_: [0 1 1]
dual_coef_: [[0. 0. 0.]
             [0. 1. -1.]]
```
assuming the 'arbitrary' values in *dual_coef_* are set to zero.

### Actual Results

For dense *X*, the fitted attributes are actually
```
classes_: [0 1 2]
support_: [0 1]              <-- should be [1 2]
support_vectors_: [[1. 0.]
                   [0. 1.]]
n_support_: [1 1]            <-- should be [0 1 1]
dual_coef_: [[ 1. -1.]]      <-- should be [[0. 0. 0.] [0. 1. -1.]]
```
For sparse *X* it raises
```
ValueError: indices and data should have the same size
```
with traceback
```

COMMENT:
@rand0wn figuring it out would be a part of solving this issue 😁 I haven't jumped deep into that part of the codebase in a while.
