libcamera: v4l2_controls: Remove V4L2ControlList class

The V4L2ControlList class only provides a convenience constructor for
the ControlList, which can easily be moved to the ControlList class and
may benefit it later (to construct a ControlList from controls supported
by a camera). Move the constructor and remove V4L2ControlList.
