Iterate over all libcamera camera properties and report them as device properties. Each libcamera ControlType is mapped to the corresponding gstreamer GType. If the ControlValue is an array of values (ControlValue::isArray()), GValue with type GST_TYPE_ARRAY is used to set the value of that ControlValue with the corresponding GType.
