[AAVE] Onboard ezETH to Arbitrum and Base Instances

Simple Summary

This is an AIP for adding borrow/lend support for Renzo Protocol and its Liquid Restaking Token (LRT) ezETH on AAVE V3 Base and Arbitrum.

Motivation

As productive assets, staking tokens are high quality collateral to borrow against. ezETH is one of the largest liquid restaking tokens. With strong demand for ezETH on mainnet this proposal seeks to provide the opportunity for Aave users to make use of ezETH on leading Layer 2 networks: Base and Arbitrum.

The onboarding of ezETH on these L2s will create increased ezETH demand and increased revenues for both Aave and Renzo Protocol, whilst also bolstering the liquidity and peg stability of ezETH.
