[Sync] Add SyncEncryptionHandler

All sync-specific encryption state (types, encrypt everything, explicit
passphrase, keys) is now tracked within the new class SyncEncryptionHandler.
It's owned by the sync manager, and unifies some of the observer logic
we previously had. In addition, it's capable of creating its own
transactions, taking us a step closer to have a nigori datatype. 

In addition, we add a NigoriHandler to abstract the chrome-side of
encryption from the sync visible side of encryption.
