Weight: `O(1)`

Send a batch of dispatch calls.
Unlike `batch`, it allows errors and won't interrupt.

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 dispatch without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).
