devnet-sdk: Go in-process backend

[protolambda]

Description

Implements an in-process Go based backend of the devnet-sdk, for faster test iteration / development cycles / efficient CI.

Features:

• interop deployment
• L1 fake-beacon CL + geth EL
• L2 op-node CL + op-geth EL, per L2 chain
• L2 op-proposer
• L2 op-batcher
• L2 op-supervisor

And composable, so each type of chain / node can be added as desired.

This also adds getter methods to the batcher and proposer services, to retrieve their RPC endpoints.

In separate PRs we'll swap interopgen for op-deployer usage (see #15059), and support the op-challenger (see #15057)

Tests

Includes a system test, that runs the system, and sees if both L2s reach block 20, as sanity-check.

This PR tracks the Go in-process implementation of the devnet-SDK system now.

The devnet-SDK interfaces work is in #14955 (base of this PR)

I think the key thing is to work out how to integrate this with the systest acquirer process so that if a kurtosis devnet isn't specified the test just spins up a suitable network. But there seems to be quite a difference in the level of detail tests provide to validate networks and what's required to spin up a new chain with this. I suspect providing defaults would work well but it will be interesting to integrate and see how to make it work in practice.

But I think this looks good generally.
