libcamera: v4l2_controls: Add V4L2ControlId
Add a V4L2 specialisation of the ControlId class, in order to construct a ControlId from a v4l2_query_ext_ctrl. The V4L2ControlId is embedded in V4L2ControlInfo, and thus needs to be copyable to allow for V4L2ControlInfo to be passed to IPAs. The ControlId copy constructor and assignment operators are thus restored, but made protected to avoid the Control class being copyable. This is needed in order to use ControlList for V4L2 controls, as ControlList requires ControlId instances for all controls.
