Make `PSA symetric decrypt: CCM*-no-tag, input too short (15 bytes)`
depend on MBEDTLS_CCM_C otherwise the multi-part test fails on
the missing CCM* instead on the input length validity for CCM*.

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.

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.

PSA_ALG_RSA_PSS algorithm now accepts only the same salt length for

Test the following combinations:
* 1024-bit key, SHA-256, salt=0
* 1024-bit key, SHA-256, salt=31 (1 byte shorter than standard)
* 1024-bit key, SHA-256, salt=32 (standard length)
* 1024-bit key, SHA-256, salt=94 (maximum possible length)
* 1024-bit key, SHA-512, salt=61 (1 byte shorter than standard)
* 1024-bit key, SHA-512, salt=62 (standard = maximum possible length)
* 528-bit key, SHA-512, salt=0 (only possible length)
Test psa_verify_hash() for both PSA_ALG_RSA_PSS and PSA_ALG_RSA_PSS_ANY_SALT
with all of these combinations. For psa_verify_message(), just test once
with the standard length and once with a different length.
Note that as of this commit, both PSA_ALG_RSA_PSS and
PSA_ALG_RSA_PSS_ANY_SALT accept any salt length during verification, hence
all the new test cases are positive.
The verify test cases were generated using the Python script below.

The requirement of minimum 15 bytes for output buffer in
psa_aead_finish() and psa_aead_verify() does not apply
to the built-in implementation of the GCM.
Alternative implementations are expected to verify the
length of the provided output buffers and to return
the MBEDTLS_ERR_GCM_BUFFER_TOO_SMALL in case the
buffer length is too small.

Only use PSA_ALG_AEAD_WITH_SHORTENED_TAG with the default tag length when
it's part of a series or when the tag length is a critical part of the test.
Don't use it when the tag length is secondary, to make the test data easier
to read.

Tests for psa_cipher_encrypt and psa_cipher_decrypt functions.
The psa_cipher_encrypt function takes no parameter for IV and always generates
it therefore there will be a randomness in the calculation and cannot be
validated by comparing the actual output with the expected output.
The function is tested by:
- doing a prtially randomized test with an encryption then a decryption
and validating the input with output of the decryption
- validating against the multipart encryption
The combination of this two methods provides enough coverage like a
known answer test.
