qcacmn: Add framework for NDP cmd execution

Add NDP command execution framework:
1) Define UCFG apis, that will be called from OS_IF layer
2) Define request proccessing functions to post to scheduler and callback.
3) Define request proccessing functions to post to serializer and callback.
4) Define functions handling activated, cancelled and timed out NDP req.
