Bence Szépkúti 08f34656cb Return the same error in multipart and single shot AEAD
psa_aead_encrypt_setup() and psa_aead_decrypt_setup() were returning
PSA_ERROR_INVALID_ARGUMENT, while the same failed checks were producing
PSA_ERROR_NOT_SUPPORTED if they happened in psa_aead_encrypt() or
psa_aead_decrypt().

The PSA Crypto API 1.1 spec will specify PSA_ERROR_INVALID_ARGUMENT
in the case that the supplied algorithm is not an AEAD one.

Also move these shared checks to a helper function, to reduce code
duplication and ensure that the functions remain in sync.

Changes
* Return PSA_ERROR_INVALID_ARGUMENT if the algorithm passed to singleshot
AEAD functions is not an AEAD algorithm. This aligns them with the
multipart functions, and the PSA Crypto API 1.1 spec.
