Many Vulkan driver allow the SPIR-V to use the `Unknown` image format for storage images and texel buffers. This makes the SPIR-V more flexible, and it useful for developers. However, it can be cumbersome to have to add the `vk::image_format` attribute to all resources. This option allows users to make `Unkown` the default image format for all resource types. Fixes microsoft#7484
