* move vulkan module setup function to global scope
* use the vulkan include setup func for module setups instead of manual linking
* test setup function extended to allow for modules
* create std module variant for each test
* remove the obsolete NO_UTILS from test setup
* commented some TODOs
* only enable module tests when VULKAN_HPP_ENABLE_CPP20_MODULES is set
* reenable handles.cpp test
* remove use nested namespaces
* include array header for ArrayProxyNoTemporaries test
* include <compare> in enums for spaceship operator
* manually added <compare> to Flags.cpp test
* properly guarded <string_view> with c++17 requirement
* Add support for vulkan_video.cppm module
Fix#2151
* Add a module version for the Video test
Currently this add vulkan_video.cppm to the VulkanHppModule target,
which might not be what we want (maybe guard this by an option(), or add
another target like VulkanVideoHppModule, etc.).
* Add a separate target for `vulkan_video.cppm`
* Extract common logic to `vulkan_hpp__setup_module`
* Fix several CMakeLists.txt issues
- Add `vulkan_video.cppm` to `VK_GENERATED_VULKAN_HEADERS`.
- Remove unnecessary ${ARGN} quotes.
- Move version checks out of `vulkan_hpp__setup_module`.
- Separate `FILE_SET_NAME` from `FILE_SET`.
