MoltenVK: Failed to create Vulkan instance when implementation supports is_portability_driver

ERROR:            vkCreateInstance: Found drivers that contain devices which support the portability subset, but the portability enumeration bit was not set!. Applications that wish to enumerate portability drivers must set the VK_INSTANCE_CREATE_ENUMERATE_PORTABILITY_BIT_KHR bit in the VkInstanceCreateInfo flags and enable the VK_KHR_portability_enumeration instance extension.
