Merge #10747

10747: fix: Remove faulty logic for ascending test attributes for runnables r=Veykril a=Veykril

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/10744

- This logic is currently not required as we do not expand test/bench anymore for the time being
- The implementation of this was flawed to begin with as it just skipped out of macro expansions instead of ascending the trees inside expansions
