Original change's description:
> Vulkan: Port renderer to Fuchsia
> 
> 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.
> 
> BUG=angleproject:2475
> TEST=angle_end2end_tests on Fuchsia
