Wifi usability: Add @SystemApi to receive Wifi usability score 



Add system API to allow framework to receive Wifi usability score from system APK.
Also add a new permission to protect this API from being used by unauthorized applications. This permission is the same as the one added for sending Wifi usability stats.

Bug: 113262380.

Test: frameworks/base/wifi/tests/runtests.sh
