Add required trait impls for OpEthApi

[mattsse]

with #9324 we now have a op type for op specific eth API

in order to reuse this type we need this type to be FullEthApi:

reth/crates/rpc/rpc-eth-api/src/helpers/mod.rs

Lines 49 to 53 in b2bbd00

	/// Helper trait to unify all `eth` rpc server building block traits, for simplicity.
	pub trait FullEthApi:
	EthApiSpec + EthTransactions + EthBlocks + EthState + EthCall + EthFees + Trace + LoadReceipt
	{
	}

this types needs to implement the Eth traits and all prerequisites.
this can be done incrementally, trait by trait.
at first, all traits should simply delegate to the inner type that also satisfies the trait.

rn this code is in https://github.com/paradigmxyz/reth/blob/main/crates/rpc/rpc/src/eth/helpers/optimism.rs, and must stay there also (i.e. be duplicate) until the type OpEthApi can be plugged in (blocked by node builder)

Working on this.
