Split DBus constants per daemon.

The service_constants.h file defines the DBus method names, property
names, signal names, property values and other DBus string constants
that define the API from Chromium to the Chromium OS system. It was
also the main way daemons in Chromium OS could talk to other daemons,
by sending DBus method calls using the method and interface names
defined here.

We are moving towards generated proxies for DBus communication packaged
in client libraries. Each daemon should expose a client library use to
talk to that daemon. The code generated from the .xml description
covers the interface names, methods names and property names, but
doesn't include property values and other required constants involved
in the interface but not expressed in the .xml file.

This patch splits the DBus constants used by Chromium and other daemons
in one file per daemon, that will eventually be part of the client
library presented by that daemon.
