Bluetooth: Update class of device on discoverable timeout
When the discoverable timeout triggers and limited discoverable mode was used, then the class of device needs to be updated to remove the limited discoverable bit. To keep the class of device logic in a central place, expose a new function mgmt_discoverable_timeout that can be called from the timeout callback. In case the class of device value needs updating, it will add the HCI command to the transaction.
