feat(lmeval): Filter protected env vars set from CR directly

[ruivieira]

The LMEval Job CR allows to set env vars directly from the CR.
This PR disables setting protected vars (i.e. related to offline and code execution), thus overriding the offline/no execution CR settings.

Refer RHOAIENG-16885.
