Nouns DAO V3 migration cleanup

I propose the second part of the migration as in my understanding everybody just waiting for this upgrade process to fully finish, therefore until it's finally finished the DAO can't function at 100% as the focus is highly diverted on this upgrade process. I included all the transactions originally planned, then top of that I added the withdrawal from the Payer contract after there was some argument for it from DAO members. This proposal is submitted less than 2 days after the first upgrade proposal (Prop 356) which means that by the time/if the first one gets executed we will also know if this proposal failed or passed, so basically if this fails the DAO can just resubmit without any delay of the planned process, but if this passes we just saved ourself from another 10 days of headache.

This proposal contains 10 transactions:

1.Move leftover ETH from treasury v1 to treasury v2 2.Approve treasury v2 to transfer lil nouns from treasury v1 3.Transfer ownership of TokenBuyer to treasury v2 4.Transfer ownership of Payer to treasury v2 5.Approve unlimited stETH to be transferred by the ERC20Transferer contract 6.Invoke ERC20Transferer to send remaining stETH to the new treasury 7.Transfer all wstETH to treasury v2 8.Transfer all rETH to treasury v2 9.Transfer all USDC to treasury v2 10.Withdraw from Payer to treasury v2
