crypto: deprecate useless crypto APIs

The APIs were probably exposed by accident. getAuthTag and setAuthTag
are not a usual getter/setter pair: Getting the authentication tag
only makes sense in the context of encryption, setting it only makes
sense in the context of decryption. Currently, both functions throw.
Neither has been documented publicly.
