Looking at the description for this function, it shouldn't be too hard
to write a proper implementation and a small test. (In particular, the
documentation claims this simply counts the number of Present() calls,
not necessarily the number of finished presents.) Note that
d3d12_swapchain_GetLastPresentCount() exists as well.
