[Wi-Fi] Fix transition mode problems

1. In AccessPoint#updateBestRssiInfo, if bestResult is available, cache if it’s transition mode at  new variables.
2. Remove SECURITY_PSK_SAE_TRANSITION & SECURITY_OWE_TRANSITION since we will cache if an Wi-Fi AP is transition mode.
3. Enhance getSecurity(ScanResult result).
   For a PSK/SAE transition mode ScanResult, return SAE.
   For a open/OWE transition mode ScanResult, return OWE.
4. Enhance all AccessPoint#matches methods
5. Use enhanced AccessPoint#matches to replace AccessPoint#isKeyEqual
6. In WifiTracker#updateAccessPoints, it associates an AccessPoint with a configured WifiConfiguration
   I. If an AccessPoint is PSK/SAE transition mode, update it with a configured network
      of the same SSID and PSK/SAE security if it’s available. (SAE has higher priority).
   II. If an AccessPoint is Open/OWE transition mode, update it with a configured network
       of the same SSID and open/OWE security if it’s available. (OWE has higher priority).

	         it should connects.
              2. Save a SAE network, click a PSK/SAE transition mode AP of the same SSID,
	         it should connects.
              3. For 1. and 2., the transition mode AP should show 'Saved'.
	      4. For 1. and 2., looking at saved network page, each saved network should
	         shows correct connection status of the transition mode AP.
