William Banfield e91bac3565 internal/consensus: proposer waits for previous block time (#7376) 
This change introduces the logic to have the proposer wait until the previous block time has passed before attempting to propose the next block.

The change achieves this by by adding a new clause into the enterPropose state machine method. The method now checks if the validator is the proposer and if the validator's clock is behind the previous block's time. If the validator's clock is behind the previous block time, it schedules a timeout to re-enter the enter propose method after enough time has passed.
