[Wi-Fi] Support WiFi detail page for OpenRoaming feature in AOSP setting.

Issue: Openroaming should have a specific detail page.
Solution: Apply the mock design to only reserve two preference items:
          1.Auto-connect
          2.Scription details

Bug: 146669261
Test: Add unit test case to test the new controller: WifiSubscriptionDetailPreferenceController2
