Instead of trying to compact the surface state table to get rid of any
unused render targets, emit MAX(1, colorAttachmentCount) surface states
always. This ensures that secondaries will always match with primaries
when we go to do the copy since there's no rule requiring the secondary
to have VK_FORMAT_UNDEFINED when the primary has a NULL image view.
