`typing` classes instantiation is considered valid by mypy

Bug Report

mypy fails to detect attempts to instantiate typing.List, which triggers runtime error

To Reproduce

Considering following example:

from typing import List
if __name__ == "__main__":
    x = List[str]([])
    print(x)

Mypy reports this code as valid, although it is guaranteed to fail at runtime:

(py_39) % python3 -mmypy mypy-instance.py
Success: no issues found in 1 source file
(py_39) % python3 mypy-instance.py 
Traceback (most recent call last):
  File "/Users/nshulga/test/mypy-instance.py", line 3, in <module>
    x = List[str]([])
  File "/Users/nshulga/miniconda3/envs/py_39/lib/python3.9/typing.py", line 668, in __call__
    raise TypeError(f"Type {self._name} cannot be instantiated; "
TypeError: Type List cannot be instantiated; use list() instead

Expected Behavior

Mypy shoudl report abovementioned construct as abstract class/non-instantiatiable type

Your Environment

• Mypy version used: 0.910
• Python version used: 3.9.4
• Operating system and version: MacOs 12.0.1

Start with the reproducer in mypy-instance.py and run it with mypy 0.910, then compare its result with the Python runtime error from Liststr. Trace how mypy handles instantiation of typing.List and make the completed behavior report this construct as non-instantiable, with a regression test for the example.
