Adds a new "setup" tag to deploy steps that can be executed ahead of
the Bedrock migration. Runs everything except the SystemDictator steps.

This caused unnecessary build errors.

ctb: Live migration utilities

specs: Update links

op-batcher/op-proposer: New package structure

op-e2e: action test conflicting sequencers

Adds some utilities to make it easier to perform a live migration:

- If a live deployer isn't configured, the SystemDictator will populate transactions for each step and output a JSON containing the transaction's `to`, `data`, `value`, and `chainId` fields. This gives us the opportunity to simulate these transactions prior to executing them, and makes it easier to generate multisignature transactions.
- The dynamic oracle config step requires user input. To make this easier, I added a Hardhat task that configures the dynamic oracle config. It operates in two modes. In send mode it will send the transaction directly. This is useful for the Goerli migration. In no send mode it outputs the raw transaction hex for simulation/multisig purposes. The task will confirm all input before sending any transactions.

tdocs: Update ToB invariants report to final version

Note: After the go module bump I can remove the replace statement here.

This places most of the files into a single folder.
