Implement VK_EXT_separate_stencil_usage

This extension allows users to query and specify different usages for the main image and the stencil. SwiftShader does not use an image's usage for non-debug purposes outside of vkGetPhysicalDeviceImageFormatProperties2. This applies to separate stencil usage as well.
