libcamera: v4l2_controls: Turn V4L2ControlInfoMap into a class
In preparation for extending V4L2ControlInfoMap with control idmap support, turn it into a real class. Make it inherit from std::map<> instead of wrapping it to keep the API simple. V4L2ControlInfoMap is meant to be constructed with a set of control info, and never modified afterwards. To ensure this, inherit from std::map<> with private access specifier, and explicitly expose the std::map<> methods that do not allow insertion or removal of elements. A custom move assignment operator is implemented to allow efficient construction of the V4L2ControlInfoMap.
