Add AP SME device feature flag to advertise that the SA Query procedures
are handled in driver.
If this flag is advertised SA Query request or response frames from peers
are not reported to userspace. Thus userspace components shall skip SA
Query specific validations.
Ex: When AP started with Operating Channel Validation(OCV) support and
channel switch occurs, hostapd starts SA Query timer for OCV enabled
STAs. Hostapd sends deauth to the STAs which didn't send SA Query
request before timeout, Hostapd can skip such validations when this flag
advertised.
