Support EIP1186 and get_Proof method

[p4u]

Are there any plans for supporting EIP1186? ethereum/EIPs#1186

This would enable the web3 get_Proof method in order to fetch a MerkleProof of a specific AVM state storage and validate it against the State Root hash by any offchain or different blockchain-based service.

Having this method available on Arbitrum would allow us integrate our voting system (https://www.notion.so/aragonorg/Introducing-Vocdoni-Bridge-cf7e73d38c4a45788358e9a1497cdf19) but it would probably enable more use-cases, specially now that Layer3 zkRollups are starting to appear.
