vulkan/state: Track the input attachment count

Browse source 
Tilers need to know, at the very least, which input attachments are
"real" input attachments which map to a color or depth/stencil
attachment in tile memory and which are "fake" input attachments that
should be treated as regular textures. To do this we need to know
VkRenderingInputAttachmentIndexInfoKHR::colorAttachmentCount, which
wasn't provided by the state tracking infrastructure. When the
VkRenderingInputAttachmentIndexInfoKHR isn't provided, we don't know it,
though, so we have to record a special UKNOWN value. In that case, the
driver will know thanks to
VUID-VkGraphicsPipelineCreateInfo-renderPass-09652 that all input
attachments are "real" input attachments that map directly to color
attachments if they have an InputAttachmentIndex.
