Evaluate core XDR change impact for adding ContractCostType::ChaCha20DrawBytes

What?

Evaluate the impact of Core XDR ContractCostType::ChaCha20DrawBytes changes in stellar/stellar-xdr@f2f213c

I don't think we need to do anything specifically for this change or #1001 because we do not construct ContractCostType xdr values in either horizon or soroban-rpc. I think the only work required is updating the xdr definitions in the go monorepo and then bumping the go monorepo dependency in soroban-rpc.

I think the work for updating the xdr definitions can be pointed as a 3 (stellar/go#4788 is a similar issue from the past which can be used as a reference point).

Closing in favor of stellar/go#5075
