If the VkPhysicalDeviceVulkan12Properties structure is included in the pNext chain of the
VkPhysicalDeviceProperties2 structure passed to
vkGetPhysicalDeviceProperties2, it is filled in with each
corresponding implementation-dependent property.
These properties correspond to Vulkan 1.2 functionality.
The members of VkPhysicalDeviceVulkan12Properties must have the same
values as the corresponding members of
VkPhysicalDeviceDriverProperties,
VkPhysicalDeviceFloatControlsProperties,
VkPhysicalDeviceDescriptorIndexingProperties,
VkPhysicalDeviceDepthStencilResolveProperties,
VkPhysicalDeviceSamplerFilterMinmaxProperties, and
