anv/pipeline: More aggressively optimize away color attachments

Instead of just looking at the number of color attachments, look at
which ones are actually used by the subpass.  This lets us potentially
throw away chunks of the fragment shader.  In DXVK, for example, all
subpasses have 8 attachments and most are VK_ATTACHMENT_UNUSED so this
is very helpful in that case.
