winevulkan: Adequate vkEnumerateInstanceLayerProperties to the Vulkan spec.

The section for vkEnumerateInstanceLayerProperties states [1]: On success, this command returns * VK_SUCCESS * VK_INCOMPLETE On failure, this command returns * VK_ERROR_OUT_OF_HOST_MEMORY * VK_ERROR_OUT_OF_DEVICE_MEMORY Always setting the layer count to zero and returning VK_SUCCESS is valid, as even if the function is given an array in pProperties, it's filled with zero layers [1]: https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/vkEnumerateInstanceLayerProperties.htmlSigned-off-by: Victor Hermann Chiletto <v@hnn.net.br> Signed-off-by: Joshua Ashton <joshua@froggi.es> Signed-off-by: Liam Middlebrook <lmiddlebrook@nvidia.com> Signed-off-by: Alexandre Julliard <julliard@winehq.org>
