Query the display status from DisplayInfo

Browse Source 
During the resolution changes, the display status in DisplayMetrics is
obsolete during the resolution changes. To get the accurate display
status, we query the status from DisplayInfo, instead of DisplayMetrics.

Bug: 233698163
Test: Switch resolution with customized density
