libcamera: v4l2_controls: Replace V4L2ControlInfo with V4L2ControlRange

Browse Source 
The V4L2ControlInfo class only stores a ControlRange. Make it inherit
from ControlRange to provide a convenience constructor from a struct
v4l2_query_ext_ctrl and rename it to V4L2ControlRange.

*
* The V4L2ControlInfo class represents all the information related to a V4L2
* control, such as its ID, its type, its user-readable name and the expected
* size of its value data.
*
* V4L2ControlInfo instances are created by inspecting the fieldS of a struct
* v4l2_query_ext_ctrl structure, after it has been filled by the device driver
* as a consequence of a VIDIOC_QUERY_EXT_CTRL ioctl call.
*
* This class does not contain the control value, but only static information on
* the control, which shall be cached by the caller at initialisation time or
* the first time the control information is accessed.
* The V4L2ControlRange class is a specialisation of the ControlRange for V4L2
* controls. It offers a convenience constructor from a struct
* v4l2_query_ext_ctrl, and is otherwise equivalent to the ControlRange class.
