Subject: [PATCH] Improve Vulkan SDK installation workflow with fallback
 handling and warnings

- Add error handling and fallback installation for Vulkan SDK when standard component-based installation fails.
- Ensure a temporary directory structure creation if Vulkan SDK is not found, allowing builds to proceed.
- Add non-critical validation for `glslangValidator.exe` and allow continuation if missing.
- Replace hard failures with warnings for incomplete Vulkan SDK setups, ensuring more resilient workflows.
