Auto merge of #52767 - ljedrz:avoid_format, r=petrochenkov
Prefer to_string() to format!() Simple benchmarks suggest in some cases it can be faster by even 37%: ``` test converting_f64_long ... bench: 339 ns/iter (+/- 199) test converting_f64_short ... bench: 136 ns/iter (+/- 34) test converting_i32_long ... bench: 87 ns/iter (+/- 16) test converting_i32_short ... bench: 87 ns/iter (+/- 49) test converting_str ... bench: 54 ns/iter (+/- 15) test formatting_f64_long ... bench: 349 ns/iter (+/- 176) test formatting_f64_short ... bench: 145 ns/iter (+/- 14) test formatting_i32_long ... bench: 98 ns/iter (+/- 14) test formatting_i32_short ... bench: 93 ns/iter (+/- 15) test formatting_str ... bench: 86 ns/iter (+/- 23) ```
