arbitrary_types_allowed does not propagate to the model which is created for a NamedTuple

# Bug

When using a NamedTuple as a field in a pydantic model, it cannot have arbitrary types - even if `arbitrary_types_allowed` is `True` on the model. I found that when `create_model_from_namedtuple` is [called](https://github.com/samuelcolvin/pydantic/blob/master/pydantic/validators.py#L561), `config` is not passed (but for `TypedDict`, it _is_ [passed](https://github.com/samuelcolvin/pydantic/blob/master/pydantic/validators.py#L585)).

Output of `python -c "import pydantic.utils; print(pydantic.utils.version_info())"`:
```
             pydantic version: 1.9.1
            pydantic compiled: True

from typing import NamedTuple

class Foo:
    pass

class Bar(NamedTuple):
    foo: Foo

class MyModel(pydantic.BaseModel):
    bar: Bar

    class Config:
        arbitrary_types_allowed = True
