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.
