This change modifies the shape of Page.getInstallabilityErrors [1] CDP
event to include the error ids and arguments that are needed to generate
the detail messages that are displayed in the Applications - Manifest
tool. The design is proposed in Localizability of CDP [2].

The strings that are currently present in installable_logging.cc will be
moved to the DevTools frontend. They'll remain in place so we are backwards
compatible. Separate CLs will be made to process the new data in the
DevTools frontend.
