[mac] Fix crash when holding RefMut while showing context menu

Other events can arrive while we are showing the context menu. To work
around this, we need to not show the menu while holding a borrow on
the window state, and instead schedule it to be shown after we've
returned.

A consequence of this fix is that, currently, we don't actually use
the x, y values passed by the caller, and instead just always use
the last known mouse position.
