VkPhysicalDeviceHostImageCopyPropertiesEXT in profiles schema differs from spec.

Vulkan spec's definition of `VkPhysicalDeviceHostImageCopyPropertiesEXT`:
```c
VkStructureType sType;
void* pNext;
uint32_t copySrcLayoutCount;
VkImageLayout* pCopySrcLayouts;
uint32_t copyDstLayoutCount;
VkImageLayout* pCopyDstLayouts;
uint8_t optimalTilingLayoutUUID[VK_UUID_SIZE];
VkBool32 identicalMemoryTypeRequirements;
```

The profiles schema says that this struct should contain only the members `optimalTilingLayoutUUID` and `identicalMemoryTypeRequirements`.

But vulkaninfo and vulkan-caps-viewer print the entire structs. Is this just a bug in the schema generator?

Compare the profiles schema definition for VkPhysicalDeviceHostImageCopyPropertiesEXT with the Vulkan specification, then trace the schema generator that produces it. Check how vulkaninfo and vulkan-caps-viewer consume the result; done means the generated schema consistently represents the complete struct.
