wifi: mac80211_hwsim: implement NAN synchronization

Add all the handling to do NAN synchronization on 2.4 GHz including
sending out beacons. With this, the mac80211_hwsim NAN device also works
when used in conjunction with an external medium simulation.

Note that the TSF sync is not ideal in case of an external medium
simulation. This is because the mactime for received frames needs to be
estimated and the simulation may not update the timestamp of beacons
to the actual time that the frame was transmitted.

The implementation has an initial short phase where it scans for
clusters. This facilitates cluster joining and avoids creating a new
cluster immediately, which would result in two cluster join
notifications. It does not scan otherwise and will only see another
cluster appearing if a discovery beacon happens to be sent during the
2.4 GHz discovery window (DW).
