Refactor of ServiceManagerContext.

In this CL, we refactor the ServiceManagerContext to make sure all of the
services can be registered without any dependency of BrowserMainLoop.
It includes the following changes:
1) Add API StartBrowserConnection() in ServiceManagerContext to start the
   browser connection to the ServiceManager. This API must be called after the
   BrowserMainLoop starts.
2) Make OutOfProcessServiceInfo takes a RepeatingCallbacks to get the process
   name.
3) ServiceMangerContext owns the DeferredSequencedTaskRunner for audio service.
   It was owned by BrowserMainloop before this CL.
