The implementation was silently overwriting the IV length to 12
even though the caller passed a different value.
Change the behavior to signal that a different length is not supported.

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.

Expected output generated by OpenSSL (see below) apart from the case
where both password and salt are either NULL or zero length, as OpenSSL
does not support this. For these test cases we have had to use our own
output as that which is expected. Code to generate test cases is as
follows:
#include <openssl/pkcs12.h>
#include <openssl/evp.h>
#include <string.h>
int Keygen_Uni( const char * test_name, unsigned char *pass, int
passlen, unsigned char *salt,
int saltlen, int id, int iter, int n,
unsigned char *out, const EVP_MD
*md_type )
{
size_t index;
printf( "%s\n", test_name );
int ret = PKCS12_key_gen_uni( pass, passlen, salt, saltlen, id, iter,
n, out, md_type );
if( ret != 1 )
{
printf( "Key generation returned %d\n", ret );
}
else
{
for( index = 0; index < n; ++index )
{
printf( "%02x", out[index] );
}
printf( "\n" );
}
printf( "\n" );
}

Add dependencies on built-in hash of signature/
signature verification and asymmetric
encryption/decryption tests. The dependency is
not added for tests based on SHA-256 as SHA-256
is always present when PSA is involved (necessary
to the PSA core) and that way most of PSA signature
/verification tests are still run when PSA hash
operations are accelerated.

Add non regression test for invalid usage of
the output buffer in psa_cipher_encrypt().
The output buffer should not be used to pass
the IV to the driver as a local attacker could
be able to control the used IV.
