Removes the config option for being able to set
the coinbase of the bedrock transition block.
It is now always set to the sequencer fee vault
predeploy. This is one less config option that needs
to be set correctly. The coinbase is always set to
the sequencer fee vault in bedrock blocks.

contracts-bedrock: deterministic storage

Makes the storage slot deterministic for the unsafe
block signer. This is useful because the `op-node` uses
a storage proof to fetch the value, so the `op-node` can
compute the storage slot value locally. This decouples
the way that `solc` lays out storage from the network policy,
making bugs less likely to happen when changing the contracts.

feat(ctb): deploy drippie to Goerli

Breaks out the SystemDictator steps into two files so that the steps
that get executed before the system is shut down can easily be separated
from the steps that executed after the system gets spun back up. Idea
here is that you would execute with the tag "steps1", wait for the
legacy system to come down, migrate the L2, then execute with the tags
"steps2" to complete the upgrade.

* op-chain-ops: Fix state migration, add post-checks

This PR fixes a bug in `op-chain-ops` that could cause state to become erroneously erased during the L2 migration. While testing the Goerli migration in check mode, I encountered an issue where `db.GetState` was returning null storage slots for the legacy message passer during the withdrawals portion of the migration. Upon further inspection, I discovered that we were using `db.CreateAccount` in the `setProxies` method. `db.CreateAccount` will erase the state associated with the passed-in address, so I updated `setProxies` to check if the account exists first. I also added a map of predeploys that should _not_ be touched as part of the migration process at all. At the end of the migration process, I iterate over these "untouchable" contracts and make sure that their code matches a preset list of code hashes and sample up to 5,000 storage slots before and after the migration to make sure the match.

Additionally, I found a bug in the witness generation data within `l2geth`. The witness generation code for the message passer does not take reverts into account. There's no easy way to do this, since we don't have access to the call frame in which the revert occurred. To work around this, I added the ability to ignore reverted storage slots in the `ParamsByChainId` structure.

Lastly, I made a few miscellaneous changes to improve our confidence in the migration script:

- I added checks to the OVM ETH migration to ensure that state slots are properly preserved.
- I added a read cache to the underlying state DB so that repeated read calls are faster.

I have verified that this migration script works end-to-end with check mode enabled against a forked Goerli L1.

* Add hash checking in addition to sampling
