Cache GetSystemMetrics values with variable template.
The variable template could be generalized like this:
template <auto F, auto... A> const auto cache = F(A...);
and instantiated like:
cache<GetSystemMetrics, SM_CXVSCROLL>
It would still be limited to constant function arguments, which
usually isn't a problem for GetSystemMetrics, but might be for
other functions.
