### Describe the bug

While the toFormData is ready to receive a FileList, the function tries to iterate it over a normal forEach which leads to a

```
TypeError: arr.forEach is not a function
    at FormData.defaultVisitor (toFormData.js:157:1)
    at each (toFormData.js:184:1)
    at Object.forEach (utils.js:256:1)
    at build (toFormData.js:183:1)
    at toFormData (toFormData.js:194:1)
    at Object.transformRequest (index.js:71:1)
    at transform (transformData.js:21:1)
    at Object.forEach (utils.js:247:1)
    at Object.transformData (transformData.js:20:1)
    at Axios.dispatchRequest (dispatchRequest.js:38:1)
```

### To Reproduce

Add a file input to the form and try to submit:
```
const FormFileInput = (props: FormFileInputProps) => {
  const { control, name, multiple } = props;
  const { field } = useController({ control, name });
  const [value, setValue] = React.useState('');
  return (
    <input
      type="file"
      value={value}
      onChange={(e) => {
        setValue(e.target.value);
        field.onChange(e.target.files);
      }}
    />
  );
};
```

Error should appear both on a single or multiple file upload.
