Cosmos-sdk Ethermint Integration

[Wizdave97]

There are quite a few chains that use ethermint which enables evm compatibility for cosmos-sdk chains

• Cronos - https://github.com/crypto-org-chain/cronos/blob/main/app/app.go#L307
• Sei - https://github.com/sei-protocol/sei-chain/blob/main/app/app.go#L337
• Injective - https://github.com/InjectiveFoundation/injective-core/blob/master/injective-chain/app/app.go#L337
• KAVA - https://github.com/Kava-Labs/kava/blob/master/app/app.go#L321
• XRPLEVM - https://github.com/xrplevm/node/blob/main/app/app.go#L231

This integration requires:

• Generic Ismp Tendermint Consensus client
• ICS23EvmStateMachine implementation that verifies EVM slot hashes using ics23 proofs
• Generic tendermint consensus relayer implementation.
