This covers adding the mechanism for encrypting backup archives, but does not yet add the hooks that perform the encryption of backups. This will instead come in a follow-up bug.

Factoring this out, as computing these keys is something that we need to do both
when generating the ArchiveEncryptionState, as well as when performing a
decryption.
This also renames "authKey" and "encKey" in ArchiveEncryptionState to use
"backupAuthKey" and "backupEncKey", as these are more in-line with what the
encryption design document uses (and because there are "authKeys" and "encKeys"
that will be used by the encryption mechanism that are distinct from the
backupAuthKey and backupEncKey).

Since the ArchiveJSONBlock uses a $ref to reference the metadata in the
BackupManifest schema, we have to change the JSON validation mechanism
we're using to one that supports $ref's.

These classes allow us to encrypt and decrypt chunks of a backup archive
if encryption is enabled.
