These are a Linux construct and should live here. Removes a weird passthrough API from FEXCore and keeps it in the frontend instead. This isn't even typically allocated in a real setup, as it's only a fallback for if VDSO isn't loaded. The CallbackReturn function stays in FEXCore because it would have caused an API in the other direction instead.
