Add curve 25519 variants of AsymmetricKey

For both Ed25519Key and X25519Key, the PKCS#8 encoded private key is
stored in the key_material_ field of the base Key class.

The i2d_PrivateKey() function in OpenSSL doesn't cope with curve 25519
keys, so extend it.

Also include helper functions that check {hw,sw}_enforced authorizations
to determine if a key is {Ed,X}25519.
