Subject: `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.
