anv: Handle VK_ATTACHMENT_UNUSED in colorAttachment

From the Vulkan 1.0.98 spec for vkCmdClearAttachments:

"If the aspectMask member of any element of pAttachments contains
VK_IMAGE_ASPECT_COLOR_BIT, then the colorAttachment member of that
element must either refer to a color attachment which is VK_ATTACHMENT_UNUSED,
or must be a valid color attachment."
