This effectively reverts commit 9ff0cc7e0fa7e99163610d2fcb58e96f3315e343. For some reason "git revert" lead to "no changes" after fixing conflicts, so a clean revert was not possible. The original issue (#57022) is no longer reproducible even with this patch, so we can remove the suppression. This is in line with our goal to make -Wenum-constexpr-conversion a non-downgradeable error, see #59036. Co-authored-by: Carlos Gálvez <carlos.galvez@zenseact.com>
