Workaround breaking API change in vkGetLatencyTimingsNV
The API of vkGetLatencyTimingsNV changed, which causes compilation failure due to the generated code using the newer API while the Vulkan-Headers may be for the old API. The fix is to just disable the function if the headers are too old. While this does limit the usage, because its from a new extension, there shouldn't be a huge impact.
