Add mutex in viem/ethers helpers

[kanej]

Initially raised here: NomicFoundation/hardhat-ignition#781 (comment)

I also got the nonce error, i rechecked my code and found out i was calling ignition module inside hardhat script for deploying, but two modules were being called at the same time, i wasn't awaiting for the promise which deploys a ignition module.
So you need to double check and make sure only one module gets deploy initiated at one time.

We should consider adding a mutex to guard against two modules being deployed at once due to not awaiting the deploy.
