           Summary: vkGetPhysicalDeviceSurfaceCapabilities2KHR passes
                    invalid VkSurfaceKHR handle to driver

Relevant log entries of Chrome failing to initialize Vulkan

Hi!

With:

    winevulkan: Use host Vulkan structures for private thunks arguments.

calling vkGetPhysicalDeviceSurfaceCapabilities2KHR (on 32-bit builds at least)
ends up passing the wrong VkSurfaceKHR handle to the driver. This can be
reproduced with "chrome.exe --use-angle=vulkan --in-process-gpu". I have
attached the relevant parts from a debug trace of a broken run, annotated with
few comments (and some extra trace points for clarity).

The issue seems to be in this generated thunk:

static NTSTATUS thunk32_vkGetPhysicalDeviceSurfaceCapabilities2KHR(void *args)
{
    ...
    convert_VkPhysicalDeviceSurfaceInfo2KHR_win32_to_host(params->pSurfaceInfo,
&pSurfaceInfo_host);
    params->result =
wine_vkGetPhysicalDeviceSurfaceCapabilities2KHR(params->physicalDevice,
&pSurfaceInfo_host, params->pSurfaceCapabilities);
    ...
}

The conversion function populates pSurfaceInfo_host.surface with the
driver_surface handle, which is not what
wine_vkGetPhysicalDeviceSurfaceCapabilities2KHR expects.

Note that the conversion works fine when we have a direct call to the driver
function, for example in the vkGetPhysicalDeviceSurfaceFormats2KHR thunk:

static NTSTATUS thunk32_vkGetPhysicalDeviceSurfaceFormats2KHR(void *args)
{
    ...
    convert_VkPhysicalDeviceSurfaceInfo2KHR_win32_to_host(params->pSurfaceInfo,
&pSurfaceInfo_host);
    params->result =
wine_phys_dev_from_handle(params->physicalDevice)->instance->funcs.p_vkGetPhysicalDeviceSurfaceFormats2KHR(wine_phys_dev_from_handle(params->physicalDevice)->phys_dev,
&pSurfaceInfo_host, params->pSurfaceFormatCount, params->pSurfaceFormats);
    ...
}

For verification I hacked thunk32_vkGetPhysicalDeviceSurfaceCapabilities2KHR to
to use the original surface in pSurfaceInfo_host and this fixed the issue for
me.

Thanks!
