Nachiket Kukade 4c76af3f68 esp_wifi: Add support for NAN Discovery and Datapath 
Update wifi lib with below -
1. Create NAN Discovery SM for beaconing & cluster formation
2. Create NAN interface for Tx/Rx of beacons & action frames
3. Add commands & events for NAN Services Publish/Subscribe/Followup
4. Add NAN Datapath definitions, Events, Peer structures
5. Support for forming and parsing of Datapath related attributes
6. Modules for NDP Req, Resp, Confirm, Term, Peer management
7. NAN Interface related additions in Datapath, Data Tx Q's

In addition include below changes -
1. Add netif and driver support for NAN Interface
2. Add simple examples for Publisher-Subscriber usecases
3. Add an advanced console example that supports commands
   for NAN Discovery, Services & Datapath
4. Add wifi_apps for providing better NAN API's and Peer management
