Cleanup format arguments (#2650)

Inlined format args make code more readable, and code more compact.

I ran this clippy command to fix most cases, and then cleaned up a few trailing commas and uncaught edge cases.

```
cargo clippy --bins --examples  --benches --tests --lib --workspace --fix -- -A clippy::all -W clippy::uninlined_format_args
