It doesn't make sense to keep the old and almost never used alternative wxClipboard implementation which has known fatal bugs (such as casts of wxDataObject that could be wxDataObjectComposite to wxBitmapDataObject, see #23564) when wxUSE_OLE is never going to be disabled anyhow. Note that this means wxSetClipboardData() function doesn't exist at all any longer when previously it was available in the wxUSE_OLE==0 builds. As the official builds always used wxUSE_OLE==1, this doesn't look like a huge loss, but if needed, we could add it back later and reimplement it in terms of wxClipboard::SetData().
