Khala Network is migrating to Ethereum and thus are being decommissioned from Kusama. This has caused the XCM channels between Moonriver and Khala to become unresponsive, so this proposal is made with the purpose of closing these channels.

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.

- **Problem Statement:** XCM channels between Moonriver and Khala are unresponsive due to Khala Network migrating to Ethereum.
- **Significance:** Ensuring smooth operations by closing unresponsive channels.
- **Proposed Solution:** Proposal to close the XCM channels between Moonriver and Khala.
- **Expected Outcomes:** Improved network efficiency and stability post closure.
