qcacld-3.0: Add support to send roam scan scheme for the triggers

Add support to handle the nl80211 attribute -
QCA_ATTR_ROAM_CONTROL_TRIGGERS_SCAN_SCHEME. Send RSO update to
firmware if roam scan scheme value is received via the nl80211
attribute QCA_ATTR_ROAM_CONTROL_TRIGGERS_SCAN_SCHEME over the
QCA_WLAN_VENDOR_ATTR_ROAMING_SUBCMD subcommand.
