Apple's Automatic Reference Counting automatically releases the Metal objects returned by VK_EXT_metal_objects. The fetchDependencies script now applies Templates/Vulkan-Headers/VK_EXT_metal_objects-unret.gitdiff to add an __unsafe_unretained ownership qualifier to the Metal object declarations in vulkan_metal.h. This should be a temporary patch until the VK_EXT_metal_objects extension can be properly modified.
