Module __getattr__ doesn't work with lazy import

[JelleZijlstra]

Bug report

Bug description:

typing.ForwardRef is defined through a module __getattr__. This breaks with lazy imports:

$ ./python.exe -c 'lazy from typing import ForwardRef; print(ForwardRef)'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    lazy from typing import ForwardRef; print(ForwardRef)
ImportError: deferred import of 'typing.ForwardRef' raised an exception during resolution

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
    lazy from typing import ForwardRef; print(ForwardRef)
                                              ^^^^^^^^^^
ImportError: cannot import name 'ForwardRef' from 'typing' (/Users/jelle/py/cpython/Lib/typing.py)

CPython versions tested on:
