Add new QCA vendor attributes for roaming configurations

Add new roam control vendor attributes to configure the roaming
parameters dynamically.
QCA_ATTR_ROAM_CONTROL_CANDIDATE_SCORE_MIN_DELTA_THRESHOLD
controls the minimum required score threshold for an AP to be
considered as a roaming candidate.
QCA_ATTR_ROAM_CONTROL_CONNECTED_BSS_RECONNECT_DISALLOW_PERIOD
configures time to enable reconnection again to the current BSSID.
