537217: [C++17] Add support for typename keyword for template template parameters

This patch allows for the 'typename' keyword to be used in
template-template template parameter declarations. Additionally, this
patch also fixes an issue in the writer, which caused the ellipsis in
variadic template-template template parameter declaration to be dropped.
