  Vulkan: Enhance SamplerDesc for YUV formats
  
  In order to uniquely identify a VkSamplerYcbcrConversion, having just
  the format is insufficient. We need to account for conversion model
  and color component range. Refactor SamplerDesc by encapsulating YUV
  related fields into its own YcbcrConversionDesc.
  
  Bug: angleproject:6732
  Test: Texture2DTestES3.*Yuv*Vulkan
