Reland "Start ServiceManger before creating BrowserMainLoop."

This relands commit aa60c219407f1158214858e83e5456e42dcfe891. The original CL
(https://crrev.com/c/1113802) got reverted becuase FeatureList and field
trials are not setup properly in early startup in Android WebView, but
ServiceMangerContext has checked features. See crbug.com/899376. The fix is
in a separate CL: https://crrev.com/c/1305876. Another related precursor CL
is: https://crrev.com/c/1308096.

This CL is an exact copy of the original CL.

The original cl description is:
This CL instantiates the ServiceManagerContext before creating
the BrowserMainRunner. It splits the startup path into two,
with/without starting the full browser. The changes are implemented
behind a flag "allow-start-service-manager-only".
