As part of this, streamline a bunch of related stuff:

• Introduce PathParser::word_sym, as an alternative to PathParser::word.
• Remove MetaItemParser::path, and just get the two parsers one at a time.
• Rename MetaItemParser::path_without_args as MetaItemParser::path, and avoid the clone.
• Inline and remove MetaItemParser::word_without_args, which has a single use.
• Remove MetaItemParser::word_or_empty_without_args, which has a single use.
• Remove MetaItemParser::path_is, which is unused.
• Remove MetaItemListParser::all_{word,path}_list, which are unused.
