Use blast sync for aod with display switch 

So the display can turn on after the AOD has presented the
redrawn appearance of new size.

Bug: 337154331
Test: Enter aod low power mode in folded state.
      Unfold the device and check the aod should not flicker.
Flag: com.android.window.flags.blast_sync_notification_shade_on_display_switch
