[Don't vote] Destroying Multichain XC-20 mintable tokens

Dear Moonbeam community! 

Due to Multichain bridge no longer serving its function in transferring assets between EVM chains and Polkadot, we propose to burn Multichain's XC-20 tokens and redeem the underlying Polkadot-native assets. The purpose is to make these assets available for use elsewhere for the benefit of the entire Polkadot ecosystem.

XC-20 tokens ids:
- xcWBTC: `278750993613512357835566279094880339619`
- xcETH: `228256396637196286254896220398224702687`
- xcUSDC: `337110116006454532607322340792629567158`

Destroy Multichain XC-20 mintable tokens

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

## Complexity
- O(C) where C is the number of calls to be batched.

- The Multichain bridge is no longer working properly.
- We want to burn the Multichain's XC-20 tokens and get Polkadot-native assets instead.
- The purpose is to use these assets for the benefit of the Polkadot ecosystem.
- The tokens we want to burn are xcWBTC, xcETH, and xcUSDC.
- This will help make things better for Polkadot.
