wifi: nl80211: add support for NAN stations

There are 2 types of logical links with a NAN peer:
- management (NMI), which is used for Tx/Rx of NAN management frames.
- data (NDI), which is used for Tx/Rx of data frames, or non-NAN
  management frames.

The NMI station has two roles:
- representation of the NAN peer - for example, the peer's schedule
  and the HT, VHT, HE capabilities - belong to the NMI station, and not to
  the NDI ones.
- Tx/Rx of NAN management frames to/from the peer.

The NDI station is used for Tx/Rx data frames of a specific NDP that was
established with the NAN peer.

Note that a peer can choose to reuse its NMI address as the NDI address.
In that case, it is expected that two stations will be added even though
they will have the same address.

- An NDI station can only be added after the corresponding NMI station
  was configured with capabilities.
- All the NDI stations will be removed before the NDI interface is brought
  down.
- All NMI stations will be removed before NAN is stopped.
- Before NMI sta removal, all corresponding NDI stations will be removed

Add support for adding, removing, and changing NMI and NDI stations.
