This does two things: * Modify `nsXULPopupManager::ShowPopup()` so it calls `ShowPopupAsNativeMenu()` as long as an anchor wasn't passed in, and only on Mac. * Modify `-[MOZMenuOpeningCoordinator _openMenu:atScreenPosition:forView:withAppearance:]` so it also takes a `aIsContextMenu` param. If the param is true, we synthesize a right-click event and pop up a context menu as usual. If it's false, we use `-[NSMenu popUpMenuPositioningItem:atLocation:inView:]` instead. The reason this works is because `-[NSMenu popUpMenuPositioningItem:atLocation:inView:]` opens the menu in a sensible place when the x-y coords are near the right edge of the screen. In contrast, `+[NSMenu popUpContextMenu:withEvent:forView:]` will anchor the menu's top-right corner to the mouse cursor when near the right edge.
