Apply synced relayout if we have FLAG_WINDOW_VISIBILITY_CHANGED

The client needs to call relayout to get the valid surface if
- mFirst,
- mViewVisibility != viewVisibility,
- mNewSurfaceNeeded, or
- mAppVisibilityChanged.

We didn't cover mNewSurfaceNeeded or mAppVisibilityChanged previously.
All of them are covered by FLAG_WINDOW_VISIBILITY_CHANGED.

Bug: 244521023
Bug: 161810301
Test: 1. Enable LOCAL_LAYOUT
      2. Open Camera and double press the power button.
      See if the preview screen of Camera become blank.
