…here unnecessary (#10236) Same as #10230, for small changes to various crates. Replace usages of `write!` macro with either `fmt.write_str(...)` for static strings or `Display::fmt` / `Debug::fmt` for other values, where it's not being used to concatenate multiple values. `Formatter::write_str` is more performant, as it avoids various checks. `Display::fmt` / `Debug::fmt` may also perform a little better in some cases, and will be equivalent in others. But in all cases it should be better for compile times, due to avoiding macro expansion and trait resolution.
