`export` support in HLSL (#2188)
* #include an absolute path didn't work - because paths were taken to always be relative.
* Compile to a dxil library.
* Added CompileProduct.
* Support handling of ModuleLibrary.
* CacheBehavior -> Cache
* Use CompileProduct for -r references.
* CompileProduct -> Artifact.
* Determining an artifact type on binding.
* Determine binary linkability.
* Added Artifact::exists.
* Added ArtifactKeep.
* Small fixes.
* Small improvements to Artifact.
* Add zip extension.
* Fix some comments.
* Fix multiple adding of PublicDecoration.
Make public output export for DXIL/lib.
Add checking for simpleDecorations such that only added once.
* Use 'whole program' to identify library build.
* Add -target dxil so test infrastructure knows it needs DXC.
