fa1bf6818f clang-format: Set InsertNewlineAtEOF: true (MarcoFalke)
Pull request description:
Now that the minimum supported clang version is 17, the `InsertNewlineAtEOF` setting can be set to `true` in the clang-format file. (https://releases.llvm.org/16.0.0/tools/clang/docs/ClangFormatStyleOptions.html#insertnewlineateof)
This is in line with the already existing newline linter. Can be tested via:
```
truncate --size=-1 src/init.cpp
git diff
# Should fail:
cargo run --manifest-path ./test/lint/test_runner/Cargo.toml -- --lint=trailing_newline
# Restore newline:
git diff -U0 | ./contrib/devtools/clang-format-diff.py -p1 -i -v
```
