The attributes module in kona-primitives contains two core types to upstream into op-alloy-rpc-types-engine.
L2PayloadAttributes
L2AttributesWithParent
op-alloy-rpc-types-engine already defines a OptimismPayloadAttributes that should serve as a drop-in replacement for L2PayloadAttributes, but L2AttributesWithParent will need to be upstreamed to op-alloy-rpc-types-engine.
Additionally, the op-alloy-rpc-types-engine should be made optionally serde, enabling the feature by default.
