feat: FIP-8 verifications for contract wallets

[horsefacts]

Motivation

Support verifications signed by smart contracts. See FIP-8 for more details.

Change Summary

Update validations to verify smart contract signatures provided in verification messages using publicClient.verifyTypedData. This function makes an RPC call to verify smart contract signatures, trying EIP-6492, EIP-1271, and ECDSA recovery in order.

Create and pass default public clients to validation functions that may need them.

Additional Context

Related protocol docs PR: farcasterxyz/protocol#129

Hubble

• Hub: Create an Optimism publicClient at hub creation time.
• Storage Engine: Add l2PublicClient. Pass public clients through to validation functions.
• Storage Engine Worker: Pass serialized RPC config to worker thread, create and pass public clients to validation functions.

Core

• New: Add eth/clients and eth/chains modules, providing default mainnet/testnet public clients.
• Validations: Pass provided or default public clients through validations to signature verifier. Validations that do not explicitly provide PublicClients will inherit the defaults.
• Crypto: Add smart contract signature verification using publicClient.verifyTypedData. This function makes an RPC call to verify smart contract signatures, trying EIP-6492, EIP-1271, and ECDSA recovery in order. Note that we don't use this for EOA recovery to avoid making an unnecessary RPC call. Instead we call the "offline" verifyTypedData util (i.e. the existing EOA signature verification behavior).
• Protobufs: Update VerificationAddEthAddressBody protobuf to add chainId and verificationType.
• Signers: Add optional chainId argument to signVerificationEthAddressClaim
• Factories: Add transient contractSignature parameter to verification factory.
