Introduce Eth/Op PayloadTypes impl

[mattsse]

Describe the feature

what we want here

reth/crates/ethereum/engine-primitives/src/lib.rs

Lines 29 to 42 in d5ddb41

	pub struct EthEngineTypes;
	impl PayloadTypes for EthEngineTypes {
	type BuiltPayload = EthBuiltPayload;
	type PayloadAttributes = EthPayloadAttributes;
	type PayloadBuilderAttributes = EthPayloadBuilderAttributes;
	}
	impl EngineTypes for EthEngineTypes {
	type ExecutionPayloadV1 = ExecutionPayloadV1;
	type ExecutionPayloadV2 = ExecutionPayloadEnvelopeV2;
	type ExecutionPayloadV3 = ExecutionPayloadEnvelopeV3;
	type ExecutionPayloadV4 = ExecutionPayloadEnvelopeV4;
	}

is something like

pub struct EthEngineTypes<T:PayloadTypes = EthPayloadTypes>;

impl<T: PayloadTypes> PayloadTypes for EthEngineTypes<T> {
    type BuiltPayload = T::BuiltPayload;
    type PayloadAttributes = T::PayloadAttributes;
    type PayloadBuilderAttributes = T::PayloadBuilderAttributes;
}


struct EthPayloadTypes;
impl PayloadTypes for EthPayloadTypes {
    type BuiltPayload = EthBuiltPayload;
    type PayloadAttributes = EthPayloadAttributes;
    type PayloadBuilderAttributes = EthPayloadBuilderAttributes;
} 

same for OP

Hi, can I work on this?
