multicluster-engine: remove plugin registries from hardcoded registries.conf

LVMS, ODF, NVIDIA and RHOAI registry entries were hardcoded in the
MCE custom-registries ConfigMap even when those plugins are not deployed.
Remove them so the existing patch_mce_registries.yaml mechanism adds them
dynamically only when the corresponding plugin is actually enabled.

Also drops the legacy openshift-service-mesh-tech-preview and
openshift-service-mesh-dev-preview-beta entries, which are no longer
needed with servicemeshoperator3.
