qcacld-3.0: Add vendor attribute for high RSSI roam trigger threshold

Browse source 
Currently the roam scan high RSSI delta is configured via INI.
Define an attribute to allow user configure high RSSI roam
trigger threshold. STA is expected to trigger roam if the current
connected AP's RSSI gets above this high RSSI threshold. STA's
roam attempt on high RSSI threshold aims to find candidates from
other better Wi-Fi bands.
This attribute value is given priority over the INI.
Use a new service bit WMI_SERVICE_5GHZ_HI_RSSI_ROAM_SUPPORT to
enable high RSSI roam trigger in 5 GHz as well.
