Document rustdoc with `--document-private-items`

The `tool_doc` macro introduced in rust-lang#86737 did not use `false` as the default value for `binary` when it is not provided, so the `if` is not even expanded and thus the argument is never provided if the `binary` argument isn't.

Resolves rust-lang#86900
