Include trailing comma in multiline Debug representation

This commit changes the behavior of Formatter::debug_struct,
debug_tuple, debug_list, debug_set, and debug_map to render trailing
commas in {:#?} mode, which is the dominant style in modern Rust code.

Before:

    Language {
        name: "Rust",
        trailing_commas: false
    }

After:

    Language {
        name: "Rust",
        trailing_commas: true,
    }
