CI: Remove file_format.sh changes hard to reproduce on Windows

Until we provide a cross-platform pre-commit hook that can perform those changes
on Windows, this only leads to a lot of frustration from Windows contributors.

The UTF-8, newline and EOF and BOM checks are still good to keep as those are
issues that we'd otherwise have to point out manually in the review.
The removed changes are mostly cosmetic and should be handled by clang-format
ideally, or by some self-developed cross-platform tooling.
