**Abstract**

Close the XCM channel  with Phala.

**Details**

As Phala is winding down from Polkadot we are proposing to close the XCM channel as leaving XCM channels open with Parachain IDs not in used can be a security problem.

**Calldata**

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.
