move feature gate checks inside IsCriticalPod
Currently `IsCriticalPod()` calls throughout the code are protected by `utilfeature.DefaultFeatureGate.Enabled(features.ExperimentalCriticalPodAnnotation)`.
However, with Pod Priority, this gate could be disabled which skips the priority check inside IsCriticalPod().
This PR moves the feature gate checking inside `IsCriticalPod()` and handles both situations properly.
