Update Mai Token implementations, unpause & enable flashloanable

Simple Summary

This proposal updates the MAI a/s/v token implementations on Optimism and Arbitrum to be aligned with Aave 3.0.2. It also unpauses the MAI reserve and sets it as flashloanable.

Motivation

In Aave v3.0.2 the signature of handleRepayment() has changed and a flashloanable flag was added. While all existing reserves a/s/v token implementations were upgraded in the original proposal and flashloanable was set to true on all reserves, shortly after, MAI was listed on the Optimism and Arbitrum pools using the old implementations and not setting flashloanable to true.

In the current state repayments of MAI could still work, as repayWithAToken is not affected, but liquidations wouldn't work as they rely on repay. To reduce risk, the Aave Guardian coordinated a pause for these mostly empty reserves (~$8'000 between Arbitrum and Optimism).

This proposal resolves the current issues by:

• Upgrading the a/s/v token implementations.
• Setting the flashloanable flashloanable flag to true.
• Unpausing the reserve.

Specification

In order to align MAI with other tokens. The proposal executes the following commands:

• POOL_CONFIGURATOR.updateAToken
• POOL_CONFIGURATOR.updateStableDebtToken
• POOL_CONFIGURATOR.updateVariableDebtToken
• POOL_CONFIGURATOR.setReservePause(AaveV3ArbitrumAssets.MAI_UNDERLYING, false)
• POOL_CONFIGURATOR.setReserveFlashLoaning(AaveV3ArbitrumAssets.MAI_UNDERLYING, true)
