Merge #1215

1215: Add clone to embassy_rp::gpio::Level r=Dirbaio a=Slushee-a

Allows you to wite a cleaner state change detector. Example:
```rs
let mut button_state: Level = Level::Low;
let mut prev_button_state: Level = button_state;

loop {
    button_state = button.get_level();

    if prev_button_state != button_state {
        led.set_level(button_state);  // Takes ownership of button_state. 
    }

    prev_button_state = button_state; // Can't be done since the ownership has been moved.
                                      // Adding Clone makes this code possible
}
```
