Investigate how to add execution tests runs on latest D3D runtime and WARP to PR and nightly builds. There were multiple cases in the past 6 months where a change in the compiler broke an execution test, and the problem was not found until the much later when the compiler and HLK tests were integrated into Windows. We need to catch these regressions sooner.

The latest D3D runtime and WARP are available as NuGet packages here:
