[Coinbase Go/No-Go] Add bonded balances to development genesis block

[raychu86]

Motivation

This PR is based on the changes made in AleoNet/snarkVM#2308.

We now pass through an optional bonded_balances variable to the START CLI to specify custom genesis bond state. Note that we still enforce that the validators must be from the set of development addresses and the number of validators must match the number specified in dev_num_validators

Example Command:

snarkos start --dev 0 --dev-num-validators 4 --dev-bonded-balances '{"validator_address_0":["validator_address_0",validator_amount_0], "validator_address_1":["validator_address_1",validator_amount_1], "validator_address_2":["validator_address_2",validator_amount_2], "validator_address_3":["validator_address_3",validator_amount_3], "delegator_address_0":["validator_address_0",delegator_amount_0]}'

Note: We may want to make this a .toml or JSON file instead.
