Bluetooth: controller: hci: Add missing DF conn-less cmds to supp list

There were missing commands in local supported commands list that
are related with connectionless direction finding.
The commands are implemented but they haven't been added
to HCI_Read_Local_Supported_Commands list.
The commit fixes that.
