The test cases use the following MPI values.
The .data file only includes those (a, b) values where a <= b, and gives the
sum unconditionally; the test code exercises a >= b and cond == 0 using these
values. The .data file gives two values for the carry out, which are for when
sizeof(mbedtls_mpi_uint) == 4 or 8.

The same elements are now also used when MBEDTLS_USE_PSA_CRYPTO
is defined and respective SHA / MD5 defines are missing.
A new set of macros added in #6065 is used to reflect these dependencies.

The same elements are now also used when MBEDTLS_USE_PSA_CRYPTO
is defined and respective SHA / MD5 defines are missing.

TEST_EQUAL(), has the benefit of outputting the values that don't match,
which can make debugging simpler.
Scope:
- Recently added new test functions
- Checks making sure the test case/data is consistent is out of scope
- Only checks where printing the values is likely to be helpful

MBEDTLS_CMAC_C dependency is ivalid.
"PEM read (unknown encryption algorithm)" needs MBEDTLS_CIPHER_MODE_CBC dependency as
otherwise this test is failing in test_when_no_ciphersuites_have_mac configuration
because mbedtls_pem_read_buffer() returns a different error (MBEDTLS_ERR_PEM_FEATURE_UNAVAILABLE).

- Improve test descriptions
- Add more test cases with return value of 1
- Remove the mbedtls prefix from the test function

MBEDTLS_SSL_IANA_TLS_GROUP_SECP192R1 and friends are not members of the mbedtls_ecp_group_id enum
Found by clang's -Wassign-enum

This is done to be able to bild test_psa_crypto_config_accel_hash component where MD5 is only available accelerated (PSA_WANT_ALG_MD5 is enabled and MBEDTLS_MD5_C is disabled) but MBEDTLS_USE_PSA_CRYPTO is disabled.
So the build should not attempt to enable pem_pbkdf1.
