Deprecate wUSDM from Arbitrum and Optimism markets

Proposal summary

WOOF! proposes to deprecate wUSDM from cUSDCv3 on Arbitrum network, and cUSDCv3 and cUSDTv3 on Optimism, since deprecation of USDM itself and its Chainlink oracle. In order to achieve this price feed on both networks will be updated to a new one, which will return the smallest acceptable price - 0.00000001 (1e-8), and the supply cup will be set to 0 to prevent further deposits. This proposal takes the governance steps recommended and necessary to update a Compound III USDC market on Arbitrum, and a Compound III USDC and USDT market on Optimism. Simulations have confirmed the market’s readiness, as much as possible, using the Comet scenario suite. Further detailed information can be found on the corresponding proposal pull request.
