wifi: iwlwifi: mld: Add support for NAN

- Add firmware API definitions related to NAN.
- Indicate support for NAN Device interface operation, if supported
  by the firmware.
- Add support for starting and stopping NAN cluster functionality.
  The NAN cluster operation is offloaded to the FW, which notifies
  the driver on:
  - cluster events: Start/Join cluster.
  - Discovery Window (DW) end, which allows the driver to flush the
    HW queues and update the higher layers
