Vulkan: Emulated RGB copies in compute The copy between emulated RGB formats can take a number of paths: - Sample from src (reinterpreted as UINT), output to dst - Sample from src, output to temp buffer, copy to dst - Copy src to temp buffer, output to dst - Copy src to temp buffer, convert to another temp buffer, copy to dst While directly sampling from src and outputting to dst is more efficient, these are not always possible. The former may not have SAMPLED_IMAGE usage bit for the reinterpreted UINT format, and the latter may not have STORAGE_IMAGE usage at all. This change takes the universal approach of using two temp buffers. The ConvertVertex shader is used to transform between RGB and RGBA when copying from the first temp buffer to the second.
