When ALG_TLS12_PSK_TO_MS() is used, first derivation is correct
but the following derivations output data is incorrect.
This is because input key is erased in psa_tls12_prf_psk_to_ms_set_key()
since commit 03faf5d2c1.
Fixes: 03faf5d2c1 ("psa_tls12_prf_psk_to_ms_set_key: clear buffers after usage")

It doesn't make sense for psa_mac_verify() to return
PSA_ERROR_BUFFER_TOO_SMALL since it doesn't have an output buffer. But this
was happening when requesting the verification of an unsupported algorithm
whose output size is larger than the maximum supported MAC size, e.g.
HMAC-SHA-512 when building with only SHA-256 support. Arrange to return
PSA_ERROR_NOT_SUPPORTED instead.

Otherwise the systematically generated algorithm-not-supported tests
complain when they try to start an operation and succeed.

Use conditional compilation flags for building ECC key derivation code consistent with flags used for mbedtls_ecc_group_of_psa().

Perform the following optimizations:
- fix used flags for conditional compilation
- remove redundant N variable
- move loop used to generate valid k value to helper function
- fix initial value of status
- fix comments

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.
