feat: add vip and simulation for IL pool deprecation

[Debugger022]

This VIP deprecates specific markets across multiple isolated pools on BNB Chain, Ethereum, and Arbitrum One.

Actions performed per market:

1. Pause Mint and Borrow actions
2. Set supply and borrow caps to 0
3. Set collateral factor to 0 (liquidation thresholds remain unchanged)

Additional actions:

• Set reward token supply and borrow speeds to 0 for all markets in the RewardsDistributor contracts.
• Set supply and borrow multipliers to 0 for markets present in the Prime contracts.

These updates safely deprecate the markets while allowing users to:

• Repay existing borrows
• Withdraw supplied assets
• Liquidate unhealthy positions

Earlier we had bridged the remaining XVS from reward distributors to BNB chain. This was the VIP: https://app.venus.io/#/governance/proposal/541?chainId=56

Should we do something similar?

Among the leftover tokens, is there a way to distinguish the % unclaimed by user and the part not consumed yet . If not let's just keep it to avoid user failing to claim rewards

I think after pausing we will have to create a seperate VIP to bridge the excess XVS.

To calculate the excess XVS we need the paused block number. So we have to wait for this VIP to execute.
