Refactor the Vulkan backend to support render passes of any format, rather than hard-coding RGBA8 or BGRA8. To test this, add a "vksrgb" config just for fun. Shaders aren't generating linear color (yet), but the SRGB attachment works. Co-authored-by: Chris Dalton <99840794+csmartdalton@users.noreply.github.com>
