Feature or enhancement

Proposal:

memoryview was made generic in typeshed in python/typeshed#12247. Mypy recently received a report (python/mypy#18053) due to it not being subscriptable at runtime:

>>> memoryview[int]
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    memoryview[int]
    ~~~~~~~~~~^^^^^
TypeError: type 'memoryview' is not subscriptable

It seems that memoryview should be made subscriptable at runtime, like other standard library classes that are generic in typeshed.

Happy to make a PR if there's agreement that this should be added.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
