For AEAD ciphers, the information contained in mbedtls_cipher_info is not enough to deduce a PSA algorithm value of type psa_algorithm_t. This is because mbedtls_cipher_info doesn't contain the AEAD tag length, while values of type psa_algorithm_t do. This commit adds the AEAD tag length as a separate parameter to mbedtls_cipher_setup_psa(). For Non-AEAD ciphers, the value must be 0. This approach is preferred over passing psa_algorithm_t directly in order to keep the changes in existing code using the cipher layer small.
