Vulkan: Fix YUV external format resolve attachment load/storeOp When YUV external format resolve attachment is used, and nullColorAttachmentWithExternalFormatResolve is true, the loadOp and storeOp are packed in color attachments.When we setup the resolve attachment, we must use the color attachment information instead of general resolve code path (where there is always a color attachment). Without this fix, the resolve attachment is always uses loadOp=DontCare which is wrong.
