Lots of ctypes issues on Windows for pyserial. Possibly related to d8b7ad6? Cc. @tungol

I'll take a look, thanks

The issue is that ctypes._FuncPtr exists now. Previously, it didn't, so the now-failing items didn't have anything to compare to and passed by default. Now that ctypes._FuncPtr exists in the stubs, stubtest finds that the runtime type of ctypes._FuncPtr is not a subtype of the stub annotation ctypes._NamedFuncPointer, and generates a failure. (the annotation ctypes._NamedFuncPointer is actually a subtype of the runtime ctypes._FuncPtr.)

I can move ctypes._FuncPtr to a different name that doesn't coincide with the name of the runtime ctypes.CDLL.__init__.<locals>._FuncPtr class, which would fix the issue by once again making the result of runtime_type = get_mypy_type_of_runtime_value(runtime) be None. That's vaguely dissatisfying, but I'm not sure what better solution is available.
