Add optimize_gas param for create_access_list

[imbenwolf]

Motivation

To override balances when simulating transactions, we need to figure out the access list for the balanceOf of a token

On Erigon, the gas is optimized so the access list returned is empty (which is different than geth). To get it anyway, we need to pass in an additional optimizeGas boolean flag for the eth_createAccessList call. Since geth is unavailable on Gnosis chain, we need to add the functionality of the PR to achieve the desired outcome.

More information: ledgerwatch/erigon#9444

Solution

This PR adds an optional optimize_gas (defaults to true) flag for the create_access_list method, that only gets applied if the node client is Erigon.

Please let me know if it's good or if I can improve anything!
