Add SpanException and SpanFormatException classes to source_maps.

It's often useful to associate source range information with an
exception in a way that will get printed along with that exception but
can be pulled out and manipulated directly. It's especially useful if
there's a common superclass/interface for doing so that can be shared
across packages. This adds that superclass.
