Improved error information when renderer creation fails

On Android, if you create a window with SDL_WINDOW_OPENGL, you can't create a Vulkan surface. The error message has been improved to reflect this, and the error is propagated back up to the application.

Also added warn level logging if the renderer couldn't be created.
