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:** Transitioning the channel from Picasso to Amplitude and establishing an outgoing HRMP channel from Amplitude to Picasso.
- **Significance:** Enhancing communication channels between Picasso and Amplitude.
- **Proposed Solution:** Accepting the incoming channel from Picasso and introducing an outgoing HRMP channel from Amplitude to Picasso.
- **Expected Outcomes:** Improved communication efficiency and collaboration between the two entities.
