Pref service: enable for user prefs in chrome behind a flag.
This:
- changes ProfilePrefStoreManager to, when the PrefService feature is
enabled, connect to the pref service, send it the user prefs
configuration and create a PrefStore that is backed by the pref
service
- changes PrefHashFilter to discard its on_reset_on_load callback after
the point where it may call it; when running in the perf service, the
callback owns a mojo connection that can be torn down at that point
- changes BrowserProcessImpl to wait for a task to run on the IO thread
before waiting for blocking IO to complete for each profile; the pref
service runs on the IO thread so waiting for a task to run there is
necessary
- fixes a bug in PrefServiceSyncableFactory where enabling the pref
service would crash if any non-user pref stores are null
