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.

Previously these tests depended on the definition from
inside the MD module, which in turn could be 32 or 64
bytes depending on whether MBEDTLS_SHA512_C was
defined. This is unnecessary, so a constant is itnroduced
instead.

Previously the whole .function file had a global dependency on
MBEDTLS_SHA1_C. This hasn't been correct for a long time:
- on principle, dependency declarations in .function files are for
compile-time dependencies;
- in practice, a number of test cases do not depend on SHA-1, as they only
use SHA-256 or SHA-512 - those cases should not be skipped in builds
without SHA-1;
- this was "taken advantage of" to skip dependency declarations for
test cases that only depended on SHA-1.
The previous commit removed the global dependency on SHA1_C; as a result
the test cases that actually depend on SHA-1 were not skipped in builds
without SHA-1. This commit fixes that by adding dependency declarations
where they belong: in the .data file.
All cases compute hashes using MD is available, or PSA otherwise; so
MD_OR_PSA is appropriate here.

Test data which is compared as a hex string now uses upper case to
match output of mbedtls_mpi_write_string() output. This removes usage

Cases where radix was explictly declared are removed in most cases,
replaced using script. bignum arguments are represented as hexadecimal

When USE_PSA is disabled and ECDSA_DETERMINISTIC is enabled, generating
ECDSA signatures via PK requires use of the hash via the MD layer (in
HMAC-DRBG, used by deterministic ECDSA).
When USE_PSA is enabled, ECDSA signatures via PK go through PSA which
always uses non-deterministic ECDSA, so does not rely on HMAC-DRBG/MD.
The condition used here is slightly too strong, but expressing exactly
the optimal condition seems more effort than it's worth for just 3 test
cases.

Using VIA_MD_OR_PSA_BASED_ON_USE_PSA was justified by the fact that
until a few commits ago, the test functions here computed hashes using
either MD or PSA, depending on whether USE_PSA was defined (which itself
was justified by the loose reasoning that "PK is USE_PSA territory").
A few commits ago, test code stopped computing hashes because the hash
values became part of the test data. PK itself does not compute hashes.
As a result, VIA_MD_OR_PSA_BASED_ON_USE_PSA is no longer justified.
There are now two kinds of tests:
- those that only rely on hash data (ECDSA, RSA PKCS#1 v1.5) should
depend on VIA_LOWLEVEL_OR_PSA as that is the minimal dependency, hence
the one used for data
- those that were the layer below PK will internally compute a hash (RSA
PKCS#1 v2.1): currently this hash is always computed using MD (on which
MBEDTLS_PKCS1_V21 depends), so legacy dependencies like MBEDTLS_SHA256_C
should be used for now. The previous dependency was morally wrong, it
didn't show in the driver-only tests only because PKCS#1 v2.1 is
disabled in this test for now.

We had a message in the data file, and were computing its hash in the
test function. It is more efficient (and simpler when it comes to
dependencies) to directly have the message hash in the data file.
It was probably this way because some test vectors provide the message
for the sake of all-in-one implementation that hash-and-sign at once.
But our API gets a hash as the input and signs it. In unit tests, this
should be reflected in the signature of the test function, which should
take a hash as input.
The changes to the .data file were done using the following python
script:
