Unrevert r141537: Add extensions::StateStore and use that instead of

ExtensionPrefs for persisting alarm state to disk.

More to come:
- context menus
- omnibox
- declarative webRequest

TBR=brettw
BUG=123366
TEST=extension alarms are still remembered after chrome restart

Change since last time: Fall back to a FailingValueStore if ValueStoreFrontend
can't open the database.
