feat(launch): default chain account balances

[aljo242]

Closes #927

What does this PR do?

Adds the DefaultAccountBalance field to Chain and MsgCreateChain. If this field is empty (sdk.NewCoins()). the behavior is unchanged. However, if it is populated, the balances of accounts that are created during keeper.ApplyRequest() are set to chain.DefaultAccountBalance.

How to test?

ignite chain serve --skip-proto -r
spnd tx profile create-coordinator --from alice   
spnd tx launch create-chain chain-1 "" "" --from alice --default-account-balance 1000test
spnd tx launch request-add-account 1 20000othercoins --from alice     
spnd q  launch list-genesis-account 1

I regenerated the proto files using make proto-gen and make proto-format so many of them were modified.

What's your reasoning to consider it should be named DefaultAccountBalance?

To me, it's a balance imposed by the coordinator. Default would mean this is the value set if the account doesn't provide a specific amount.

But it can be argued as well we can name it to "default" because this the balance that will be defined by default or accounts at first before the chain is launched and coins are moving

Looks great

Yeah, I agree default doesn't make as much sense as I originally thought. I'm going to change it back to AccountBalance

Hey @aljo242 is it ready for reviews?

I also wanted to add that we should add a test case in TestApplyRequest for the particular case the balance is defined

But I realize the current structure of TestApplyRequest is hard to maintain and should be improved first #944
