Prototype `eth_multicallV1` RPC API endpoint

[pistomat]

Describe the feature

There is an ongoing effort to standardise an endpoint for a multicall across execution clients and introduce a new RPC method eth_multicallV1, which allows users to make complex RPC calls to Ethereum nodes. Compared to eth_call, it has many new additional features such as multiple dependent calls, various new overrides or simulating multiple blocks.

This endpoint is not finalised yet, but implementing it will help it's development.

Additional context

The specification for this RPC method can be found here: ethereum/execution-apis#484

I think this is similar to

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

Lines 72 to 79 in ca9f236

	/// Simulate arbitrary number of transactions at an arbitrary blockchain index, with the
	/// optionality of state overrides
	pub async fn call_many(
	&self,
	bundle: Bundle,
	state_context: Option<StateContext>,
	mut state_override: Option<StateOverride>,
	) -> EthResult<Vec<EthCallResponse>> {
