libcamera: control_ids: Keep draft controls last

Let's try not to mix draft controls and regular controls.

Draft controls are unstable by definition, and removing or adding them
should not impact the enumeration of stable controls.

Keep draft controls at the end of the control_ids.yaml file and
add a comment to make clear where the draft controls section begins.
