PSA_AEAD_DECRYPT_OUTPUT_MAX_SIZE macro

A sufficient output buffer size for psa_aead_decrypt(), for any of the supported key types and AEAD algorithms. If the size of the plaintext buffer is at least this large, it is guaranteed that psa_aead_decrypt() will not fail due to an insufficient buffer size. See also #PSA_AEAD_DECRYPT_OUTPUT_SIZE(\p key_type, \p alg, \p ciphertext_length).
