Move typing_extensions to stdlib

[hauntsaninja]

I'm not sure what the best way to do this is. This effectively orphans
types-typing-extensions, but maybe that's not really a problem. (We can
yank the package too)

See #5229 (comment)
for some details, could also help issues like #5065

[srittau]

Let's try this!

[JukkaL]

This makes sense. To fix mypy primer, I think that we'll need to sync typeshed afterwards.

[JelleZijlstra]

The hard question might be what to do about types-typing-extensions on PyPI. Can we just remove it? Or is it already being used, perhaps by people using other typecheckers than mypy?

[hauntsaninja]

Fwiw, https://grep.app/ doesn't really show any usage. Mypy hasn't made a release either. I wouldn't be surprised if most usage was in typeshed and mypy CI. However, we have published other stub packages that declare dependencies on types-typing-extensions, so I wouldn't yank it. I propose merging and making an announcement issue.
