Add the on_off call in the move_to_level_with_on_off command (#1754)

* Implement the `move_to_level_with_on_off` command 

Implement the `on_off` call in the `move_to_level_with_on_off` command for the MCU Tuya devices.
The previous implementation was removed in #1748. Originally introduced in #1489

* Fix black coverage
