Issue #13274 requested logging whether the VK_KHR_bfloat16 is supported at runtime. I have added the detection for the feature to ggml_vk_print_gpu_info, and tested it on windows with the latest Nvidia GeForce Game Ready Driver (where it reported 0) as well as the Nvidia Vulkan 1.4 Developer Beta Driver (where it reported 1).
I have not tested Linux or any GPUs other than my laptop RTX 4060.
