Convert operator.not_ to torch.logical_not (#94626)
If the input to operator.not_ is a tensor, I want to convert the operator to a torch.logical_not. This allows the following test case to pass. Beforehand it resulted in the error `NotImplementedError("local_scalar_dense/item NYI for torch.bool")`
```
def test_export_tensor_bool_not(self):
def true_fn(x, y):
return x + y
def false_fn(x, y):
return x - y
def f(x, y):
return cond(not torch.any(x), true_fn, false_fn, [x, y])
```
