Interop: substitute finalizer deriver component with supervisor backend

[protolambda]

With interop devnet v1, the safe signal is currently assumed to be cross-safe still upon processing in the op-node finalizer component, and thus fine to promote to cross-finalized.

In later interop iterations we want to substitute the finalizer for L2-finality determination by the op-supervisor.

See ethereum-optimism/design-docs#70 for context on how the op-supervisor backend can maintain finality data.

The module that then maintains the safety-index can be embedded into the op-node, for non-interop chains to not run an op-supervisor service, while still doing local interop (historical events proving) and potential one-way interop with L1 (pulling events from L1 like you would from L2).
