This commit extracts Tag, Span, Text, as well as source-related debug facilities into a new crate called nu_source. This change is much bigger than one might have expected because the previous code relied heavily on implementing inherent methods on `Tagged<T>` and `Spanned<T>`, which is no longer possible. As a result, this change creates more concrete types instead of using `Tagged<T>`. One notable example: Tagged<Value> became Value, and Value became UntaggedValue. This change clarifies the intent of the code in many places, but it does make it a big change.
