Change `Token::interpolated_to_tokenstream()`.
It is currently a method of `Token`, but it only is valid to call if `self` is a `Token::Interpolated`. This commit eliminates the possibility of misuse by changing it to an associated function that takes a `Nonterminal`, which also simplifies the call sites. This requires splitting out a new function, `nonterminal_to_string`.
