Can you check that there are tests that run multiple semantic passes with various kinds of decorators? There is a small risk that this might break something.

I run all test cases where top-levels processed twice (second time gives an extra iteration). I have found no failures related to this change. I however added another attrs specific decorator test case just in case.

Fixes #6953
I first thought about actually not modifying them in
attrsplugin, but this is non-trivial, plus there are few places apart from the plugin where we modify decorators. So for now I just restore them after each iteration (in the same way we do this for overloads and other things).
