Return std::unique_ptr from svt::AcceleratorExecute::createAcceleratorHelper
...to prevent errors like 5ac6e00274e732435b55c2908db9cea658fe549b "Memory
leak"

Clear all m_pVCLMenu->pItemList->maItemList[i]->m_pSubMenu
...even if no correpsonding xPopupMenu proxy has been set up for some i
(because
that sub-menu has never been opened by the user). Otherwise, the Menu that
m_pVCLMenu->pItemList->maItemList[i]->m_pSubMenu points to will be deleted
(during a recursive xSubMenuManager->dispose call), and when later for some
sub-menu j > i that /has/ been opened by the user SetPopupMenu is called,
that
can lead to

looking at the dangling pSubMenu pointer (and even if the dangling pointer
is
never dereferenced, UBSan will try to determine whether the static_cast in
return static_cast<PopupMenu*>(pData->pSubMenu);
in Menu::GetPopupMenu, vcl/source/window/menu.cxx, is fine and cause a
crash).
