Translate Chainspec constructors to accounts code/balance/state

[MarekM25]

In the chainspec file at https://github.com/NethermindEth/nethermind/blob/master/src/Nethermind/Chains/chiado.json, there are many constructors. Constructors are not supported in Geth. We need to translate this chainspec to a version without constructors (use code, balance, storage instead)
