qcacld-3.0: Add support for the NAN Enable/Disable commands

Browse Source 
Add changes in the NAN component and Target IF to support the
NAN Enable and Disable commands. Add changes to support all
the other generic NAN commands as well. Add a state machine
to keep track of the status of the NAN Discovery in the Target.
