libcamera: controls: Store control name in ControlId
The ControlId class stores a pointer to the control name. This works fine for statically-defined controls, but requires code that allocates controls dynamically (for instance based on control discovery on a V4L2 device) to keep a list of control names in separate storage. To ease usage of dynamically allocated controls, store a copy of the control name string in the ControlId class.
