[EXPLORER] Large taskbar icon support (#5465)

Browse Source 
- Use HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\TaskbarSmallIcons
  registry key to store the icon size setting for the taskbar.
- If the registry value is missing, small icons will be used by default.
- If the registry value is set to 1, it will also use small icons.
- Only if the value exists and is set to 0 it will use large icons. This allows us
  to use the same registry value as Windows 7 explorer, while also keeping
  the taskbar icons small in most cases, especially running the shell
  on unmodified Windows Server 2003.
