Hostapd: redefine data structure to avoid dependency on IHostapd@1.2

This commit is to remove dependency on IHostapdHal@1.2 by re-defining
structures that were imported earlier. This allows support on targets
where IHotapdHal@1.2 is not present

Additionally, this commit adds following vendor network params:
 - enableOCV
 - enableBeaconProtection
