WIP: Compute test running on CPU (#1023)

* * Simplify some of test code around CPPCompiler
* Test using 'callable' with pass-through
* Small cpu doc improvements

* Improvements to Clang output parsing.

* Remove temporary file (base filename) .

* Improve handling of external errors - handle severity.

* On error dumping out to 'actual' file for runCPPCompilerCompile.

* Small fixes.
Set the source language type correctly for pass thru.

* Remove warning for test for clang backend c

* Preliminary work around making render-test compute potentiall work with CPU.
Made ShaderCompiler -> a stateless ShaderCompilerUtil.
Means we don't require a Renderer interface to do shader compilation.

* Refactor such that CPU test can take place in without Window or Renderer.

* Hack to look for prelude in source file directory.
Fix bug returning the SharedLibrary for HostCallable.

* Compute test running on CPU.

* Need the prelude currently in same directly as test.

* Hack to remove warning - that then produces an error on appveyor build.
Disable running render CPU test on non-windows.

* Improve handling of disabling CPU tests on linux.

* Added bit-cast.slang working on CPU.
