The `fmtlib` text formatting library, when compiled in C++20 onwards, requires that the incoming format string is a compile-time constant so it's able to perform type checks against it[1]. The change here ensures it can do so. While we're not set to go to C++20 any time soon, this is a backwards compatible change that can be done today and allows us to focus on the harder fmt-related issues later. No change in performance or functionality was observed. [1] https://godbolt.org/z/qG5dsf7YG Pull Request: https://projects.blender.org/blender/blender/pulls/129272
