cmake: Disable modules if clang-scan-deps is missingvulkan-sdk-1.3.290.0v1.3.290vulkan-sdk-1.3.290
clang ships the clang-scan-deps tool separately from the compiler, making it possible that the clang compiler supports modules but cannot be used by CMake for VulkanHppModule. The straightforward solution is to, when using clang, check that the scan deps tools was located. This prevents people who are using clang but not the modules from being unable to use Vulkan-Headers when the clang-scan-deps tools is missing.
