Discovery: Add `opel` key to the execution layer #10926

We can move V5 bootnodes to the superchain registry and use the ENR text format. It's also possible to use DNS discovery for the EL (a little important b/c reth does not yet support discV5 but is moving in that direction.).

V5 can be cross network. We will want to split EL and CL. Long term we may want to remove testnet bootnodes & just have mainnet bootnodes.

Right now most bootnodes are stored as enodes in our code but should be ENRs.

Status Update:

We did split out our CL bootnodes from our EL bootnodes
We're not going to switch from enodes -> ENR
We did switch to V5 on the EL
We need to add a opel key with a chainID/forkID value to the EL V5.
