This change is in preparation for adding support for emitting https://tc39.es/source-map/ source map information for jaxprs, so the relationship between a jaxpr and its Python code can be visualized using tooling for that purpose. This change adds a new `source_map()` pretty printer document, which causes the pretty-printer to populate a source_map side output during pretty printing. The change also teaches the core jaxpr pretty printer to populate source map information on each equation.
