Retry rustfmt with a larger max_width on bailed-out items.

When a generated struct field type, trait header, or function signature exceeds rustfmt's default 100-column max_width on an unbreakable path, rustfmt abandons formatting the enclosing item or function header. In rs_bindings_from_cc output, that leaves whole structs, impl blocks, or function headers collapsed onto a single line and skips normalize_doc_attributes on their #[doc = "..."] attributes, which also shifts post-formatting provenance comment counts for subsequent items.

Filter the first-pass output for lines exhibiting unformatted tokens_to_string patterns (extending function headers ending in { to their matching closing }) and run a targeted second pass with --unstable-features --file-lines and max_width=10000, while pinning sub-expression width heuristics (fn_call_width, struct_lit_width, chain_width, etc.) to their defaults so rustfmt skips sibling items via AST span intersection and inner calls still wrap normally.
