The UI code for nodes uses `stringstream`s a few times to format strings. In some cases it is fine, but in others it makes localization hard or impossible to do properly, as explained in #92758. This commit replaces some `stringstreams` by `fmt::format()`, a library that is already used in other parts of Blender and was suggested by Hans Goudey (@hooglyboogly) in [D15996](https://archive.blender.org/developer/differential/0015/0015996/#inline-138440).
