py: Re-implement controls geneneration
The Python bindings controls generation was not very good. It only covered the enums and they were in the main namespace. This adds the controls somewhat similarly to the C++ side. We will have e.g.: libcamera.controls.Brightness libcamera.controls.AeMeteringModeEnum.CentreWeighted Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
