Scale px udfps HW related sizes to curr resolution

AuthController calculates the size of UDFPS based on
the native resolution which can change. This CL updates
the lock icon view and udfps keyguard view so that the
sizes and paddings are updated based on the scaled pixel
values to account for any changes in the display's resolution.

Test: manually change display-mode with
  adb shell cmd display set-user-preferred-display-mode 1080 2340 0 0
  and then check location & size of the lock icon + udfps on keyguard
