Handle deferred evaluation of annotations in Python 3.14

[cdce8p]

Closes #10149

[cdce8p]

We should wait until we can test 3.14 in CI before merging this.

I also don't really like that we need to duplicate a lot of tests. Maybe we can come up with a better solution for dealing conditional errors in our tests.

Great !

Agree, so it's Blocked by pylint-dev/astroid#2731 and then the pylint equivalent.

Maybe time to design something to be able to expect something different according to the version ?
filename.py

something = 1 # [unused-variable|>=3.13,missing-module-docstring]

With filename.3.14.txt for the expected output of 3.14, filename.txt for the default expected output if the interpreter does not have its specific output file...

Explored something like this in #10382. The diff here would look much better, see 379ab07.

LGTM, but blocked by preliminary MRs.

This PR would is ready now. Even without 3.14 in CI yet, this could be helpful to move #10467 forward. Tested the functional tests locally with 3.14.0rc1. The remaining issues are unrelated to the changes here.

[Pierre-Sassoulas]

Really nice ! Let's merge before the 3.14 PR as you said.
