Exclude `*args` and `**kwargs` from ANN401

[jpy-git]

Describe the bug
I like the new ANN401 rule added in the v2.8.0 release.

However, one place where it's pretty common to use Any is in annotations for *args and **kwargs since they often (not always) can take mulitple types.

To Reproduce

def foo(*args: Any, **kwargs: Any): ...

gives

test.py:1:10: ANN401 Dynamically typed expressions (typing.Any) are disallowed
test.py:1:23: ANN401 Dynamically typed expressions (typing.Any) are disallowed

Could we make checking these either an option to ANN401 or we could exclude them from ANN401 and make ANN402 should someone want to disallow Any for these unpackings?

I think this should be fairly straightforward, since the argument type is already being classified. I'll have to think about what error code approach I like best for the adjustment.
