## Summary In #10341, we fixed some false positives in `.pyi` files, but introduced others. This PR effectively reverts the change in #10341 and fixes it in a slightly different way. Instead of changing the _bindings_ we generate in the semantic model in `.pyi` files, we instead change how we _resolve_ them. Closes #10509.

Summary
This PR fixes the following false positive in a
.pyistub file:In a
.pyfile, this is invalid regardless of whetherfrom __future__ import annotationsis enabled or not. In a.pyistub file, however, it's always valid, as an annotation counts as a binding in a stub file even if no value is assigned to the variable.I also added more test coverage for
.pyistub files in various edge cases where ruff's behaviour is currently correct, but where.pyistub files do slightly different things to.pyfiles. In the process of doing this, I discovered #10340.Test Plan
