Click the search result "System Sounds" will crash the Settings app

Root Cause: Preferences in this page need to pass CachedBluetoothDevice or will finish the page imediately

Solution: theses preferences are in device detail page which will only show when device get connected. Show them in search result is not reasonable. Remove them.

Bug: 270508779
Test: verfiy it did not show in search result
