[PATCH 0/2] MR6948: Vulkan object rework hotfixes.

[Aida Jonikienė (＠DodoGTA)]

This allows 32-bit DXVK games (like NFS Underground) to work again
after the recent Vulkan changes.

[PATCH 1/2] winevulkan: Mirror function handling in vk_is_available_instance_function32().

[Aida Jonikienė]

From: Aida Jonikienė

32-bit DXVK doesn't find the surface creation function without this.

[PATCH 2/2] win32u: Define some Vulkan defines earlier.

[Aida Jonikienė]

From: Aida Jonikienė

The alignment of some Vulkan structs doesn't match the winevulkan
Unix library otherwise (causing strange segfaults on 32-bit).

We should probably move these to `ntuser_private.h`, instead of including `wine/vulkan.h`:
```
#define VK_NO_PROTOTYPES
#define WINE_VK_HOST
#include "wine/vulkan.h"
#include "wine/vulkan_driver.h"
```

And then remove it from `win32u/vulkan.c` and from `win32u/d3dkmt.c`

I was thinking about getting rid of `WINE_VK_HOST` and using `WINE_UNIX_LIB` in `vulkan.h` instead. We could also default to no prototypes for unixlibs too.
