Original change's description:
> Add support for Ycbcr Conversion Samplers in vulkan.
>
> The only thing missing from this CL is that we need to bake the
> ycbcr conversion samplers into the VkPipeline when we create it. As that
> is a larger change, that will be broken up into a few follow on CLs.
>
> Currently this only supports ycbcr conversion samplers when used with
> external textures.
