feat(evmutil): Add DeployedCosmosCoinContracts query (#1605)

* add QueryDeployedCosmosCoinContracts proto * also implement protobuf marshaler for InternalEVMAddress * setup iteration & collection for deployed addrs * rewrite grpc query tests * support querying for all deployed contracts * support querying by cosmos denom * fix & test pagination * remove unused iteration methods * add CLI query command * update changelog * update spec * add InternalEVMAddress.MarshalJSON test

 `AllowedCosmosDenoms` can be altered through governance.

 ### EVM-Native Assets

 ERC-20 tokens native to the EVM can be converted into an `sdk.Coin` in the Cosmos ecosystem. This works by transferring the tokens to `x/evmutil`'s module account and then minting an `sdk.Coin` to the receiver. Converting back is the inverse: the `sdk.Coin` of the initiator is burned and the original ERC-20 tokens that were locked into the module account are transferred back to the receiver.
