Update Art Service to be a LocalManager

This CL re-names the ArtService class to conform to the Frameworks
naming convention for local managers, which are SystemServer only
"service" singletons which are accessible through the LocalManagers
registry.  The build system is updated for these changes, as well as
adding appropriate API tracking build targets.

Test: build, boot, and inspect log
