Vulkan: Add depth/stencil surfaces. This change lets us create egl::Surfaces from a D24S8 config. This is a bit hacky, because the spec only mandates 24 -or- 32 bit depth support, but not both or either individually. Will need follow-up work for proper EGL config setup. A single depth buffer is allocated for the entire set of swapchain images and is used with each. This also might be a problem if we're rendering to multiple frames at the same time. We'll likely have to revisit this in the future as well. This adds a new RenderTargetVk to the SurfaceVk class which points to the Depth/Stencil image. Since ImageViews must refer to either the depth or stencil, but not both, we'll need to address this when we get to implementing depth/stencil texture reads in shaders.
