Make set_span take mut self

This was a mistake in https://github.com/rust-lang/rust/pull/77614

It's not a _huge_ deal, because backends can always implement this with interior mutability, but it's nice to avoid interior mutability when possible. For context, the `set_source_location` method, called alongside `set_span`, also takes `&mut self`.
