Vulkan: Free up 5 bits in RenderPassDesc Leveraging the fact that there are only a handful of depth/stencil formats, the last element of RenderPassDesc::mAttachmentFormats can contain other information in addition to the depth/stencil format ID. The FormatID enum is rearranged such that depth/stencil formats are placed first, as a result occupying values in [1, 7]. These values take up 3 bits in an element of RenderPassDesc::mAttachmentFormats (which could be the last element if all color draw buffers are attached). As a result, the upper 5 bits of the last element of RenderPassDesc::mAttachmentFormats is unused. It is intended for these bits to be used in the implementation of multisampled-render-to-texture depth/stencil renderbuffers.
