LangID is a LANGID and LayoutID is a KLID: keyboard layout ID.
See terminology at http://archives.miloush.net/michkap/archive/2004/11/27/270931.html
These tables of MUI_LAYOUTS for each language, correspond to the
intl.inf LCID map:
```
; List of locales.
; <LCID> = <Description>,<OEMCP>,<Language Group>,<langID:HKL pair>,<langID:HKL pair>,...
```
where:
- each MUI_LANGUAGE entry corresponds to one such locale description;
- each MUI_LAYOUTS entry corresponds to a <langID:HKL pair>.
See http://archives.miloush.net/michkap/archive/2006/10/14/825404.html
for some details.
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.
Providing quick access of Control
Panel "Add/Remove Programs".

bAppwizMode in ParseCmdAndExecute
function.
- Add CAppDB::GetAvailableCount method.
- Add CMainWindow::CheckAvailable method.
