Subject: [PATCH] FRP bypass defense in the settings app
Over the last few years, there have been a number of
Factory Reset Protection bypass bugs in the SUW flow.
It's unlikely to defense all points from individual apps.
Therefore, we decide to block some critical pages when
user doesn't complete the SUW flow.
Test: Can't open the certain pages in the suw flow.
