Add DisplayVk and WindowSurfaceVk subclasses for Fuchsia to the vulkan renderer, as well as an implementation of OSWindow that renders fullscreen for the test suite. Disallow use of the vulkan loader from third_party as Fuchsia uses a fork of the loader and has not sent those changes upstream yet. Add a small wayland-inspired library libfuchsia-egl to provide a type "struct fuchsia_egl_window" to use as EGLNativeWindowType. This type combines a zx_handle_t to an image pipe channel and a surface size. Image pipes can only be used once to create a VkSurfaceKHR. This means we have to recreate the pipe in tests that call eglCreateWindowSurface more than once with a single OSWindow, or the second call will fail. Add a resetNativeWindow() method to accomplish this.
