Remove a `Span` from `TokenKind::Interpolated`.
This span records the declaration of the metavariable in the LHS of the macro. It's used in a couple of error messages. Unfortunately, it gets in the way of the long-term goal of removing `TokenKind::Interpolated`. So this commit removes it, which degrades a couple of (obscure) error messages but makes things simpler and enables the next commit.
