wifi: refactor Wi-Fi generation UI enhancements

- Use WifiInfo.getWifiStandard API to get active connection capability
- Use ScanResult.getWifiStandard API to get capability of a BSS
- Consider active connection is 11ax ready capable when connection
  is 8SS capable and AP is HE capable
- Consider a BSS is 11ax ready capable when device is 8SS capable and
  AP is 8SS and HE capable
- Add support for Wi-Fi generation UI enhancements in WiFitrackerLib
- Remove deprecated legacy code
