Rollup merge of #113993 - nyurik:ref_format_errors, r=WaffleLapkin
Optimize format usage

Per #112156, using `&` in `format!` may cause a small perf delay, so I tried to clean up one module at a time format usage. This PR includes a few removals of the ref in format (they do compile locally without the ref), as well as a few format inlining for consistency.
