This together with adjusting the inclusion define allows for the build to not fail with latest Vulkan-Headers that contain the stabilized Vulkan AV1 decoding definitions. Compilation fails currently as the AV1 header is getting included via hwcontext_vulkan.h -> <vulkan/vulkan.h> -> vulkan_core.h, which finally includes vk_video/vulkan_video_codec_av1std.h and the decode header, leading to the bundled header to never defining anything due to the inclusion define being the same. This fix is imperfect, as it leads to additional re-definition warnings for things such as VK_STD_VULKAN_VIDEO_CODEC_AV1_DECODE_SPEC_VERSION. , but it is not clear how to otherwise have the bundled version trump the actually standardized one for a short-term compilation fix.
