[clang-format] Reorganize RawStringFormat based on language Summary: This patch changes the structure for raw string formatting options by making it language based (enumerate delimiters per language) as opposed to delimiter-based (specify the language for a delimiter). The raw string formatting now uses an appropriate style from the .clang-format file, if exists.
