The test suite test_suite_psa_crypto_op_fail now runs a large number
of automatically generated test cases which attempt to perform a
one-shot operation or to set up a multi-part operation with invalid
parameters. The following cases are fully covered (based on the
enumeration of valid algorithms and key types):
* An algorithm is not supported.
* The key type is not compatible with the algorithm (for operations
that use a key).
* The algorithm is not compatible for the operation.
Some test functions allow the library to return PSA_ERROR_NOT_SUPPORTED
where the test code generator expects PSA_ERROR_INVALID_ARGUMENT or vice
versa. This may be refined in the future.
Some corner cases with algorithms combining a key agreement with a key
derivation are not handled properly. This will be fixed in follow-up
commits.

Determine key types that are compatible with an algorithm based on
their names.
Key derivation and PAKE are not yet supported.

Test that hash operation functions fail when given a hash algorithm
that is not supported or an algorithm that is not a hash.

The new test suite psa_crypto_op_fail is intended for systematically
generated test cases that ensure that cryptographic operations with
invalid parameters fail as expected. I intend invalid parameters to
cover things like an invalid algorithm, an algorithm that is
incompatible with the operation, a key type that is incompatible with
the algorithm, etc.
This commit just creates the infrastructure. Subsequent commits will
add data generation and test code.

CCM*-no-tag is currently available whenever CCM is, so declare
PSA_WANT_ALG_CCM_STAR_NO_TAG whenever PSA_WANT_ALG_CCM is declared and vice
versa.
Fix dependencies of test cases that use PSA_ALG_CCM_STAR_NO_TAG: some were
using PSA_WANT_ALG_CCM and some had altogether wrong dependencies.
This commit does not touch library code. There is still no provision for
providing CCM support without CCM*-no-tag or vice versa.

Generate "with implication" and "without implication" usage test cases
separately.
The set of generated test cases is unchanged. The order, and the description
of "with implication" test cases, changes.

* Remove expected_output_data: since asymmetric encryption is randomized,
it can't be useful.
* The decryption check needs the private exponent, not the public exponent.
* Use PSA macro for the expected ciphertext buffer size.
* Move RSA sanity checks to their own function for clarity.
* For RSAES-PKCS1-v1_5, check that the result of the private key operation
has the form 0x00 0x02 ... 0x00 M where M is the plaintext.
* For OAEP, check that the result of the private key operation starts with
0x00. The rest is the result of masking which it would be possible to
check here, but not worth the trouble of implementing.

Add a call to `mbedtls_md_starts()` in the `mbedtls_md_process()`
test, as it violates the API usage. Fixes#2227.

MBEDTLS_HAVE_TIME_ALT implies MBEDTLS_HAVE_TIME, so an extra
check for MBEDTLS_HAVE_TIME is not needed.
