Style: Mark clang-format 16 as supported for pre-commit hook

It only introduced a difference in a .glsl file, which I've worked
around by removing an empty line. This keeps formatting consistent
between clang-format 15 and 16.

Also added a change in the 3-to-4 project converter to fix bogus
formatting in clang-format < 17.

(cherry picked from commit 49f4860ce3e4122e17c869229701f7d86aa6956c)
