Integrate Request evm env filling in ethapi

[mattsse]

creating the TxEnv based on the TxRequest is done via:

reth/crates/rpc/rpc-eth-types/src/revm_utils.rs

Lines 119 to 123 in edbbc96

	/// Configures a new [`TxEnv`] for the [`TransactionRequest`]
	///
	/// All [`TxEnv`] fields are derived from the given [`TransactionRequest`], if fields are `None`,
	/// they fall back to the [`BlockEnv`]'s settings.
	pub fn create_txn_env(block_env: &BlockEnv, request: TransactionRequest) -> EthResult<TxEnv> {

which currently requires OP feature

reth/crates/rpc/rpc-eth-types/src/revm_utils.rs

Lines 174 to 175 in edbbc96

	#[cfg(feature = "optimism")]
	optimism: OptimismFields { enveloped_tx: Some(Bytes::new()), ..Default::default() },

this should be abstracted into a trait, ref:

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

Line 268 in edbbc96

pub trait Call: LoadState + SpawnBlocking {

Ideally something new ConfigureEvmCallEnv or similar

can I take this?

@nkysg
for the initial pr I'm fine with keeping the feature and simply move the function as is into a trait that is implemented on EthApi

[nkysg]

@mattsse OK
