Some small fixes with Windows/DX usage (#2797)

* Correct case of windows.h includes

* Use Slang::SharedLibrary to load directx dlls

* s/max/std::max/

* Factor common OS code in calcHasApi

* Add DXIL test for compute/simple

* s/false/FALSE for calls to WinAPI functions

* Factor common OS code in gfxGetAdapters

* 2 missing headers

d3d12sdklayers for ID3DDebug

climits for UINT_MAX

* Define out unused function on Linux

* Only try to load Vulkan and CUDA on Windows or Linux

* simplify D3DUtil::getDxgiModule

* Remove WIN32_LEAN_AND_MEAN &co from source files

Add a global define

* Set WIN32_LEAN_AND_MEAN &friends in headers

Restore previous state also

* regenerate vs projects
