change(wifi): NAN security_cfg as pointer

Browse Source 
security_cfg in wifi_nan_publish_cfg_t / wifi_nan_subscribe_cfg_t is a
large struct; pass it by pointer so callers don't bloat their cfg copy.
Driver deep-copies during publish/subscribe, so caller may free right
after the API returns. Add NULL-check when security_reqd is set.

Update both example apps to declare a local security_cfg and assign its
address. Add help text on EXAMPLE_NAN_SECURITY_ENABLED.
