Ed25519 Signature mode.

This mode shall be used to realize Ed25519 as described in RFC 8032 (https://www.rfc-editor.org/rfc/rfc8032). In particular

• the size of the input message can be arbitrary
• the dom2(f,c) hash prefix is the empty string as specified in Section 5.1 of RFC 8032

NOTE: To be able to perform an Ed25519 signature generation using this mode, the private key handle must be properly linked to a key handle for the associated public key using the function mcuxClKey_linkKeyPair. This is necessary to make the public key accessible during an Ed25519 signature generation. If this is not satisfied the Ed25519 signature generation will fail. If the key pair has been generated using the mcuxClKey_generate_keypair function, this linking step is already performed by mcuxClKey_generate_keypair.
