wifi: add support for 60GHz band in WifiScanner

Add new Wifi bands to include WIFI_BAND_60_GHZ.
WIFI_BAND_24_5_6_60_GHZ and WIFI_BAND_24_5_WITH_DFS_6_60_GHZ were
added and shall be used for performing full scan.

Add new addResults function which receives the full ScanData and
updates mBandScanned in addition to the scan results.
This function is used when consolidating scan results from
multiple interfaces, each one containing different bands.

isFullBandScanResults function was added and returns true in case
2.4GHz and 5GHz bands are included in the scan results, as scan results
from other bands may not be present.
