Batcher Metrics

By removing some code duplication and a more efficient implementation
of the MaxRLPBytes test.

Reusable event metrics modules.

RefMetrics are a reusable metrics module to enable block reference metrics.

The caller of BlockToBatch is sometimes interested in the L1BlockInfo
of the block, so instead of re-extracting it again, we just return it
here.

This is similar to PayloadToBlockRef but takes an interface instead that
e.g. a types.Block fulfills. This way, we can directly extract L2BlockRefs
from type.Blocks that have a valid L1 Info Deposit tx as first tx.

A block could also be converted into an ExecutionPayload, but this would make an
inefficient roundtrip, marshalling and unmarshalling all transactions.

op-proposer: log L2OutputOracle version + address

Logs the L2OutputOracle version and address after building
a client to call it. This is generally useful information to
have and future implementations of the `op-proposer` will
need to function differently depending on the version to keep
the software compatible with both permissioned and permissionless
output proposal submission.

30 seconds is too long, it feels like the script is broken.

fix(ci): reintroduce changesets patch

This doesn't fully solve the problem that we need to bump both the
FeeCap and FeeTip by 10% for geth to accept it, but it handles it
slightly better than it did.
