Interop: op-supervisor local-safe data-ingestion from op-node

[protolambda]

The op-node must feed into the op-supervisor, the op-supervisor does not rely on the EL for state. The op-supervisor was pulling safe and finalized from the EL (this originated from prototype code), intending to retrieve local-safe, but it was the cross-safe. Creating a cyclic dependency, keeping cross-safe stuck at genesis.

To fix this, we need to modify the op-node/rollup/interop deriver to emit RPC updates to the op-supervisor when local-safe data changes.

The op-node side was updated. Will open an issue to track the remainder of the work on op-supervisor.
