Lifecycle management for PolicyProviders

The ConfigurationPolicyProviderKeeper (and therefore the individual ConfigurationPolicyProviders) is now a member variable of the BrowserProcess instead of a singleton. This fixes memory leaks at the cost of slightly more complicated shutdown (the PolicyProviders must die while the file thread is still alive, but the preference system observing the providers for policy changes lives longer than that).

BUG=66054, 66102
TEST=existing unit tests; valgrind
