vulkan: Fix win/i386 calling convention

This fixes the following error when compiling with a modern
version of Clang for Windows/i386:

src/libavutil/hwcontext_vulkan.c:738:32: error: incompatible function pointer types initializing 'PFN_vkDebugUtilsMessengerCallbackEXT' (aka 'unsigned int (*)(enum VkDebugUtilsMessageSeverityFlagBitsEXT, unsigned int, const struct VkDebugUtilsMessengerCallbackDataEXT *, void *) __attribute__((stdcall))') with an expression of type 'VkBool32 (VkDebugUtilsMessageSeverityFlagBitsEXT, VkDebugUtilsMessageTypeFlagsEXT, const VkDebugUtilsMessengerCallbackDataEXT *, void *)' (aka 'unsigned int (enum VkDebugUtilsMessageSeverityFlagBitsEXT, unsigned int, const struct VkDebugUtilsMessengerCallbackDataEXT *, void *)') [-Wincompatible-function-pointer-types]
            .pfnUserCallback = vk_dbg_callback,
                               ^~~~~~~~~~~~~~~
