Commit 02fe9f5bdf introduced linking the
Windows build of the demos with d3d12 and dxgi, while also still linking
to libvkd3d-utils.la. That happens to more or less work on Wine; we get
vkd3d-utils' D3D12CreateDevice(), and Wine's
IDXGIFactory2_CreateSwapChainForHwnd(), but because Wine's
implementation of d3d12 swapchains uses vkd3d, we're able to use the
resulting swapchain buffers even though the instance of vkd3d used by
Wine may not be the same instance of vkd3d used by the demos. Perhaps
unsurprisingly, things don't go nearly as well on Windows.
We could of course stop linking the demos to vkd3d-utils on Windows, but
that's not that interesting; we're trying to show what vkd3d can do
here, not what d3d12 can do.

macOS tigetstr() takes a non-const char *, so account for that as well.
VKD3D_CHECK_FUNC does not use a fake prototype (char gettid(void);)
and does not include <unistd.h>. It always fails with Clang 16 and
GCC 14 and other compilers which do not support implicit function
declarations.
The location of dxcompiler should be set during configuration with
'DXCOMPILER_LIBS=-L/path/to/dxcompiler', and then at runtime with
LD_LIBRARY_PATH, WINEPATH or PATH as applicable.
A new 'fail(sm<6)' decoration is needed on many shader declarations
because dxcompiler succeeds on many shaders which fail with fxc. The
opposite case is less common and is flagged with 'fail(sm>=6)'. A few
tests cause dxcompiler to crash or hang, so these are avoided using
[require], which now skips tests until reset instead of exiting. Also,
'todo(sm<6)' and 'todo(sm>=6)' are used to separate checking of results.
