Support flake8-pep585 for accesses from typing after import

[wookie184]

Ruff catches all of these as UP035 violations:

from typing import (
    Container,
    Callable,
    AsyncIterable,
    Mapping,
    Coroutine,
    OrderedDict,
)

However, none of these trigger that rule:

import typing

a: typing.Container
b: typing.Callable
c: typing.AsyncIterable
d: typing.Mapping
e: typing.Coroutine
f: typing.OrderedDict

This isn't something supported by pyupgrade (as the autofix would be quite complicated), but it seems like it would be worth a warning. flake8-pep585 catches these.

Note that the names I listed are just examples, there are probably more pep 585 names with the same issue.

I agree that we should flag these. They can probably go under the existing pyupgrade rules (even if we can't fix them right now). We do have most of the machinery we'd need to fix these, but that can be a separate effort.
