Issue: A scalar with `elements` or `test_elements` argument  of `isin()` doesn't work 
Labels: triaged,module: python frontend,topic: fuzzer

### 🐛 Describe the bug

[isin()](https://pytorch.org/docs/stable/generated/torch.isin.html):
- A scalar(e.g. `3`, `4`, `5`, etc) with `elements` or  `test_elements` argument doesn't work. <- Problem(Bug)
- A scalar without `elements` or  `test_elements` argument works.

```python
import torch

t1 = torch.tensor([3, 4, 5])
t2 = torch.tensor(4)

torch.isin(elements=3, test_elements=t2) # Error 1
torch.isin(elements=t1, test_elements=4) # Error 2
torch.isin(t1, test_elements=4) # Error 3

torch.isin(3, test_elements=t2)
torch.isin(3, t2)
# tensor(False)

torch.isin(t1, 4)
# tensor([False, True, False])

""" ↓↓↓ Additional ↓↓↓ """

torch.isin(elements=t1, test_elements=t2)
torch.isin(t1, test_elements=t2)
torch.isin(t1, t2)
# tensor([False,  True, False])
```

### Error 1:

```
TypeError: isin() received an invalid combination of arguments - got (test_elements=Tensor, elements=int, ), but expected one of:
 * (Tensor elements, Tensor test_elements, *, bool assume_unique, bool invert, Tensor out)
 * (Number element, Tensor test_elements, *, bool assume_unique, bool invert, Tensor out)
 * (Tensor elements, Number test_element, *, bool assume_unique, bool invert, Tensor out)
```

### Error 2:

```
TypeError: isin() received an invalid combination of arguments - got (test_elements=int, elements=Tensor, ), but expected one of:
 * (Tensor elements, Tensor test_elements, *, bool assume_unique, bool invert, Tensor out)
 * (Number element, Tensor test_elements, *, bool assume_unique, bool invert, Tensor out)
 * (Tensor elements, Number test_element, *, bool assume_unique, bool invert, Tensor out)
```

### Error 3:

```
TypeError: isin() received an invalid combination of arguments - got (Tensor, test_elements=int), but expected one of:
 * (Tensor elements, Tensor test_elements, *, bool assume_unique, bool invert, Tensor out)
