op-node,contracts-bedrock: dynamic gas limit via SystemConfig

[protolambda]

Description

Dynamic gas limit: we extend the SystemConfig on L1 with a setter that emits gas limit changes, which can then be picked up during derivation, and applied to the payload attributes for block building.

Changes:

• extend SystemConfig contract with gaslimit setter, and require minimum gas limit for deposit / chain safety
• update chainops to deploy L1 contracts with gas limit
• new action test to test gas limit update via system config contract
• minor e2e / action test updates to handle new gas limit attribute and minimum gas limit
• update engine API types with new gas limit field
• extend system config with gas limit field
• check gas limit field when comparing payload attributes and block
• handle gas limit update events
• spec updates to describe config value, derivation and engine API usage.
• bindings update
• system config storage layout update
• minor test/utils updates to handle new field

This PR depends on ethereum-optimism/op-geth#22

Once the geth PR is merged we can update the geth dependencies, and marge this PR. A temporary go.work entry points to the geth PR for now to make CI run.

Tests

Added an action test to cover the derivation changes, and the block body validation changes in the engine.

This PR depends on ethereum-optimism/op-geth#22

I can pull in that commit in the go.work, but I'd prefer to first resolve the dependency stack of this PR, which also depend on open geth changes.

hey @protolambda, it seems like there's a lot of system config changes, this PR should just be the dynamic gas limit

[protolambda]

@trianglesphere yea, I was planning to rebase this once the sys config changes land (so close, just need op-geth PR). Github just exploded the diff here because the base branch changes. The actual changes are much smaller. I'll rebase it again

Hmm, devnet is failing on contract deployment, meaning it's failing to deploy the system config. Likely hitting the new require statement on minimum gaslimit. What gas limit do we start it with?

[protolambda]

Found the issue: the L2 gas limit is set to 0, the genesis generator then uses 15M when it's unspecified, but does not implement this same fallback when inserting the gaslimit value into the initialize args.

[trianglesphere]

This is looking pretty good. One contracts question to see if we can limit the foot guns with setting the L2 gas limit.

Merging so we can fix Hive.
