Message : Vulkan: Add ImageHelper::getIntendedFormatID() This adds helper API to return intendedFormat directly from ImageHelper object instead of vk::Format, to make API symmetrical. It is also necessary. It is also needed in some places where we no longer have access to vk::Format any more due to refactoring.
