Vulkan: Make room in RenderPassDesc for resolve attachments Data in RenderPassDesc is packed better to make room for resolve attachments (9 bits made available; 8 for color and 1 for depth/stencil). mColorAttachmentRange contains values in [0, 8). The right side of the range is made inclusive (i.e. [0, 7]) so it will fit in 3 bits. The number of samples is always a power of 2, and below 128 (for the foreseeable future), so its log is stored instead in 3 bits. This change doesn't add support for resolve attachments yet, but is split off the one that does to simplify it.
