move memory_infra and tracing to the GRC service

memory_instrumentation::Coordinator is exposed by the browser service
right now, which was a temporary solution before the
resource_coordinator service was created. This CL moves it to the
resource_coordinator service.

Also, this CL exposes the tracing service, too. Later it will be used
instead of the tracing controller that lives in the browser.

Moving memory instrumentation and tracing to the resource_coordinator
service will let the service manager to register all "service"
processes to report memory usage and trace data. This is not possible
if memory instrumentation and tracing live in content_browser since it
will be a layering violation to have a dependency from
//services/service_manager to content.
