Move wxMSW wxMenu::GetWindow() down to wxMenuBase.

GetInvokingWindow() can only be used for the popup menus which have the
invoking window, so add a new function which can be used to get the window
associated with any kind of menu in all ports -- it already existed in wxMSW
but is needed elsewhere too.
