    [USER32_APITEST] Improve user32:PrivateExtractIcons test (#5209)
    
    - Improve the test by examining total number of icon groups in files
      and by adding more testcases including two new icon files.
    - Add new ROS.ico file which has both a normal icon and a PNG one.
    - Add tests for explorer.exe and new ROS.ico and sysicon.ico files.
