ci: Update various D3D-related deps
This change updates:
- DirectX-Headers to the latest 1.613.1 which includes the work graph APIs, and ExecuteIndirect 1.1 which will be used by dzn/d3d12 to handle draw ID.
- Agility SDK to 1.613.1 which includes support for ExecuteIndirect 1.1 and shader model 6.8
- DXIL.dll to the latest March 2024 release which includes validator support for shader model 6.8
- WARP to the latest 1.0.11 which includes support for shader model 6.8 (as well as a couple bugfixes)
- zlib to 1.3.1
To prevent the build break from #10803 (closed) from impacting CI, this also includes a fix for it, as well as a couple other fixes for things that have been wrong but uncaught by testing until these new dependencies show up.
