Vulkan: Upgrade RGB8 textures to RGBA8. It's unlikely any real hardware supports this format. Hack in a fixed fallback format for RGB8. We could consider implementing conditional support by checking the VkPhysicalDevice properties. This extends the Vulkan format support info in the RendererVk class to distinguish between a Buffer and Texture format. This is closely related to how Vulkan has separate format support bits for Linear Textures, Optimal Textures, and Buffers. We probably won't need to keep separate caps for Linear/Optimal, but it makes sense for Buffers to eventually use the same format tables.
