ISACOV : Add ifdef to avoid VCS compilation error due to unsupported 'with' key word
Created by: AyoubJalali
As we discuss, for the CVA6 env we have a vcs compilation error related to the vcs version, the 'with' isn't supported for now, the fix is programmed for July, so to integrate the ISACOV in the CVA6 env, I add ifdef (a final solution after a lot of discuss) as a temporary fix.
