Vulkan API uses Flags and FlagBits for enumerations. The FlagBits contains the options that can be hold with the Flags data type. This wasn't well understood at the beginning of the project and the FlagBits where used where Flags should have been used. This cleanup fixes this, improving the readability of the code where bit manipulations where used. Pull Request: https://projects.blender.org/blender/blender/pulls/114459
