Add `format_in_format_args` and `to_string_in_format_args` lints Fixes #7667 and #7729 I put these in `perf` since that was one of `@jplatte's` suggestions, and `redundant_clone` (which I consider to be similar) lives there as well. However, I am open to changing the category or anything else. r? `@camsteffen` changelog: Add `format_in_format_args` and `to_string_in_format_args` lints
