Implement GetAllData and GetStorageKey. Also add TypedURLSyncBridge to
be an observer of HistoryBackend.
Change storageKey using big endian, since user event is using big endian, and it is better to unify our number style.

The following 4 functions are ported from TypedUrlSyncableService.
GetErrorPercentage()
WriteToTypedUrlSpecifics()
ClearErrorStats()
FixupURLAndGetVisits()
