Following up from https://bugs.webkit.org/show_bug.cgi?id=223229. In that bug, two of three issues identified were fixed with .clang-format updates. But formatting empty braced initializers as `{ }` rather than `{}` was not.

I guess this problem still exists for current trunk clang-format. https://github.com/llvm/llvm-project/issues/93635 But this problem could be solved like https://github.com/llvm/llvm-project/commit/f9022ddba4dd26dea5d04dbcd3c256d2d42b3bad technically, currently in consulting.
