Support for AVVkImage (hwcontext_vulkan.h)

[00f8t]

Hi! First of all, thank you for maintaining FFmpeg.AutoGen — it's a really helpful project!

I noticed that the current version of FFmpeg.AutoGen does not expose the AVVkImage structure from the FFmpeg Vulkan hardware context (libavutil/hwcontext_vulkan.h). This structure exists in the native FFmpeg headers and is quite useful when working with Vulkan hardware-accelerated video pipelines.

Do you have any plans to add support for AVVkImage in future versions of the wrapper?

Here’s the original struct definition for reference (from FFmpeg 7.0):

typedef struct AVVkImage 
{
    VkImage image;
    VkDeviceMemory memory;
    VkImageLayout layout;
} AVVkImage;

Having this structure available in the C# bindings would make it much easier to interoperate with Vulkan rendering backends.

Thanks again for your work!
