This class shouldn't be really used directly but document it just to make the
interface header valid C++ as this class was used as parameter type but never
defined.
Closes#14006.

Implement support for wxHELP for wxMSW, wxGTK and wxOSX/Cocoa (at least when
showing the message box from the main thread, there doesn't seem to be any way
to show more than three buttons with CFUserNotificationDisplayAlert() so
"Help" button is not supported when using it).
This is useful not only on its own, i.e. to allow the user to ask for help,
but also because it brings the total number of buttons supported by the
message dialog to 4, meaning that more choices can be offered to the user
(which is rarely, but not quite never, useful).

Microsoft documentation provides explanations as to how the icons should be
used in the message dialogs which can be useful for people wondering which
icon style to use an when.

Use the task dialog instead of the legacy message box for wxMessageDialog
implementation under wxMSW on recent (Vista and later) Windows versions.
As part of this change, remove wxMessageDialogWithCustomLabels and integrate
its functionality in wxMessageDialogBase itself as it's now used by all
platforms.

Use "wxWindows licence" and not "wxWidgets licence" (the latter doesn't
exist) and consistently spell "licence" using British spelling.

Call gtk_window_set_keep_above() to force the message dialog to be above the
other windows (some WMs do this by default anyhow but not all).
