Check orientation when retrieving FP location

Instead of relying on the orientation change display listener,
always return the most up to date fingerprint sensor
location based on the current display rotation.

Also make sure to take into account any scaleFactors
in case the resolution of the device changes.

Test: atest AuthControllerTest
Test: rotate the device on the lock screen
(ie: 0 => 180 degrees => 90 degrees => 270 degrees => 90 degrees, etc)
and authenticate with FP from each orientation. See the auth ripple
appears from the correct location (where the FP sensor is).
