feat: stateOverride usage with eth_estimateGas

[TateB]

Component

Anvil

Describe the feature you would like

geth recently added the optional stateOverride parameter to eth_estimateGas, with the same functionality as eth_call (see ethereum/go-ethereum#27800, ethereum/go-ethereum#27845). would be super useful to have this added to anvil!

example usage: estimating the total gas of an approve and transfer transaction, before the approve transaction has been done

let state = state::apply_state_override(overrides.into_iter().collect(), state)?;
