builtins: remove object.__annotations__

[JelleZijlstra]

Not all objects have annotations, so I think this shouldn't exist.
We already have __annotations__ attributes explicitly set on the
objects that do have them (e.g., functions, classes, and modules).

Not sure what the fallout of this is going to be; it might not be worth changing.

[JelleZijlstra]

This seems promising, we'll just have to add __annotations__ to a few other classes.

[JelleZijlstra]

The openlibrary change is a true positive, at least on 3.14 where accessing .__annotations__ on instances will no longer work. Submitted internetarchive/openlibrary#10753 to fix it.

Not sure about the steam.py one; it seems to be using annotations in an odd way. cc @Gobot1234

The other three should go away with the changes I'm about to push.

[Gobot1234]

In steam.py I'm using it for data parsing I don't think my use case is crazy out of the ordinary but I can stomach adding __annotations__ to StructMessage

[JelleZijlstra]

You might need to use type(self).__annotations__ but haven't looked deeply at the code.

CI breakage seems due to a release of click 20 minutes ago https://pypi.org/project/click/8.2.0/
