SDL - add SDL_WINDOW_VULKAN and make Android_CreateWindow only create an EGLSurface when SDL_WINDOW_VULKAN is not present. This makes it so the ANativeWindow* can be used with vkCreateAndroidSurfaceKHR, otherwise it will fail because having both an EGLSurface and VkSurfaceKHR attached to a window is not allowed according to the Vulkan spec: 

"In particular, only one VkSurfaceKHR can exist at a time for a given window. Similarly, a native window cannot be used by both a VkSurfaceKHR and EGLSurface simultaneously"
