wifi: rtw89: advertise missing extended scan feature

Browse Source 
Add support for random serial number in probe request and
configure channel dwell time. Advertise corresponding feature flag
NL80211_EXT_FEATURE_SCAN_RANDOM_SN and NL80211_EXT_FEATURE_SET_SCAN_DWELL.
Use the scan request duration as channel dwell time when it is
non-zero, otherwise use the default value.
