Subject: CPU compute testing on non windows targets (#1045)

* WIP: Refactor of CPUCompute and stand alone cpu-render-test

* Fix compilation on CygWin.

* Make CPU compute tests run on non windows targets.

* Check that C/C++ compiler is available for CPU compute.

* Fix some tabbing issues.

* Add -fPIC on gfx

* Use dxcompiler_47.dll from slang-binaries on windows.

* make https for git module slang-binaries

* Fix comment in premake5.lua around d3dcompiler_47.dll

* Add resources to the CPUComputeUtil::Context to keep in scope.

* Fixes problem compiling on cygwin where dx12 is included in build of gfx lib.
