* WIP with hierarchical enums.

* Some small fixes and improvements around artifact desc related types.

* Improvements around hierarchical enum.

* Fixes to get Artifact types refactor to be able to execute tests.

* Attempt to better categorize PTX.

* Work around for potentially unused function warning.

* Typo fix.

* Simplify Artifact header.

* Small improvements around Artifact kind/payload/style.

* Added IDestroyable/ICastable

* Add IArtifactList.

* First impl of IArtifactUtil.

* Use the ICastable interface for IArtifactRepresentation.

* Added IArtifactRepresentation & IArtifactAssociated.

* Add SLANG_OVERRIDE to avoid gcc/clang warning.

* Fix calling convention issue on win32.

* Fix missing SLANG_OVERRIDE.

* First attempt at file abstraction around Artifact.

* Added creation of lock file.

* Move functionality for determining file paths to the IArtifactUtil.
Add casting to ICastable.
