QQuickMenu: fix mnemonics for dynamic action/submenu items

Previously mnemonics worked only for "normal" menu items, but not for
dynamically created menu items that present actions and sub-menus. This
patch fixes the issue by specifying the menu as a QObject-parent for
such dynamically created items, because QQuickShortcutContext is based
on QObject-hierarchy.
