IppParser service api + namespace change

Changed service name to IppParser and namespace to ipp_parser.

Added the new IppParser service API, since ServiceManager is being
deprecated. New API launches an IppParser service instance in an isolated,
sandboxed process.

Bug: chromium:945409
Test: confirmed service startup configuration
