qml: adjust volume when control bar is scrolled (in addition to the volume widget)

Close #26200. This is how VLC 3 behaves, except it does not support high precision adjustment unlike here.

Request review @chub. I did not use hotkey, because I want to handle high precision mouses here as well like we do in the volume widget.
