Converts `package:` import uris into `/packages/` modules. Also renames the output modules to append `.lib.js` instead of just `.js`. This allows us to distinguish between modules and applications based on extension. Updates DDC source map code to be able to convert absolute file uris in sources so that they are relative to the source map.
