[Wi-Fi] Show Pie+x Wi-Fi icon when a connected Wi-Fi is not default route

From Android 11, a connected Wi-Fi network may not be default route
if rating provider thinks it has bad connection quality. Framework
service will keep the Wi-Fi connection but uses other connection as
default route.

This change shows Pie+x Wi-Fi icon for a connected Wi-Fi network which
is not default route.
