profile: Add a way for each ProfileKeyedServiceFactory to specify its user prefernces.

To allow us to compile individual features in/out of a chrome build, we need to
attack browser_prefs.cc, which is a giant static registration. This used to be
done through another big code path starting in ProfileImpl which call
browser::RegisterUserPrefs() which linked to other static methods. Now this is
done through overridding ProfileKeyedServiceFactory::RegisterUserPrefs(), and
there are no additional dependencies.

BUG=none
TEST=none
