Make sure display config is updated when cutout is changed

1. LocalDisplayAdapter.LocalDisplayDevice#updateDeviceInfoLocked
   posts to display thread when receiving onOverlayChanged. So
   the operation depends on it should run sequentially.

2. After updating latest display info, the cutout may affect
   the height of status bar, then it still needs to compute
   display config again after that for screenHeightDp.

Bug: 222572231
Test: Toggle different types of cutout in developer options,
      Either: rotate the display, there won't be a blank area
      or switch to another activity, there won't have another
      display config change CONFIG_SCREEN_SIZE.
