[SHELL32][CONTROL] Added basic IOpenControlPanel support (#6248)

Add a basic IOpenControlPanel implementation that supports Vista canonical registry names.

Implements `control.exe /name company.name [/page id]` and `IOpenControlPanel`
handling of Vista-style canonical registry names.

The documented `Microsoft.*` names don't work because they are simply not
in our registry but "[Executable Control Panel Items](https://learn.microsoft.com/en-us/windows/win32/shell/how-to-register-an-executable-control-panel-item-registration-)" registered by 3rd-party ISVs
will function correctly in control.exe and the COM API.

Notes:

- `IOpenControlPanel` is implemented in CControlPanelFolder.cpp because
  it is supposed to have tighter integration with that shell folder than
  it does in this PR.

- `IOpenControlPanel` is also supposed to handle .cpl files with canonical
  names registered under [`Extended Properties`](https://learn.microsoft.com/en-us/windows/win32/shell/how-to-register-dll-control-panel-item-registration-#step-3) but the control panel folder
  does not implement `IShellFolder2::GetDetailsEx` yet, so it will have to wait.

- These "Executable Control Panel Items" are also supposed to be displayed
  in the control panel itself but this PR does not address that. The
  `ITEMIDLIST` format for those needs investigation...

- The Wow64 handling is perhaps not correct but it does not matter,
  `ShellExecuteEx` gets to deal with whatever is in the `...\shell\open\command` key.
  `CControlPanelFolder` would have to take more care when it starts
  reading those keys so it knows when to append "(32-bit)" to the display name.

- `%s%s` because .cpl canonical names don't have the `::` prefix according
  to Geoff Chappell.

- Always returns `CPVIEW_CLASSIC` because our `CControlPanelFolder` does
  not support the category view.
