Add @disjoint_base decorator to the third-party stubs

[brianschubert]

Follow up to #14699

Based on the stubtest errors -- I haven't looked at the source.

Mostly mechanical additions of @disjoint_base, but see separate commits for special cases in gevent and pywintypes.

@AlexWaygood strange how shard 1 seems to be just idling, even after restarting. If I'm reading the logs right, it's finishing the old/new runs for one project (dacite), but isn't starting runs for the next project?

[brianschubert]

I tried bisecting through the primer projects to see if there's a particular project that's causing the primer stall. I think I've narrowed it down to an issue with materialize. It seems that there's exception being raised during its setup, which for some reason isn't being properly logged and re-raised in runs with many projects. I guess that's leading to some sort of deadlock in the async code?

I assume that NoReturn was used to signal that this type isn't instantiatable. So this is likely a behavior change.

[brianschubert]

Hmm yes, I was hoping *args: Never would do the trick, but it seems not.

Switched back to the original signature and added a # type: ignore for the mypy error:

stubs\pywin32\win32\lib\pywintypes.pyi:20: error: Value of type variable "_TC" of "disjoint_base" cannot be "Callable[[VarArg(Never)], Never]"  [type-var]

Pity we don't have a more pleasant way of marking uninstantiable types... ;-)
