Start button's context menu: open the Windows Start menu or the Win+X menu

Shift+click on the start button opens the Windows Start menu, and
Shift+right-click the Win+X menu, but nothing in the menu says so; a user
who doesn't know the shortcuts can't reach either. The right-click menu
now has them as their own section at the top: "Start Menu (Windows)" and
"Win+X Menu" (Windows 8 and later, where both exist).

They do exactly what the shortcuts do: post SC_TASKLIST 'WSMK' to
Progman (the -togglenew path) and ShowWinX().

The first label reuses Menu.StartMenu, which is already translated in 41
languages for the Start Menu (Windows) item. Menu.WinXMenu is new, English
only for now. The Operation section of the help mentions both.
