These changes make the Clang parser recognize parameter pack expansion in attribute arguments and consume them if the attribute is marked as supporting parameter pack expansions.
Currently only the `clang::annotate` attribute will support parameter pack expansions in its arguments. The parser will issue an error diagnostic if other attributes are passed parameter pack expansion arguments.
