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.

The code will make the decision based on availability of MD, not of
MD+this_hash. The later would only be possible at runtime (the hash
isn't known until then, that's the whole point of MD), so we'd need to
have both MD-based and PSA-based code paths in a single build, which
would have a very negative impact on code size. So, instead, we choose
based on the presence of MD, which is know at compile time, so we only
have one of the two code paths in each build.
Adjust the macros so that they match the logic of the code using them.

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.

Previously MD_C was auto-enabled based on the fact that ALG_RSA_PSS was
requested, but that's no longer the case since the previous commit.
We can fix this in one of two ways: either enable MD_C, or enable all
the PSA_WANT_ALG_SHA_xxx that are needed for test. Go for MD_C because
it's a single line and avoids having to enumerate a list that might grow
in the future.

Test coverage not there yet, as the entire test_suite_pkcs1_v21 is
skipped so far - dependencies to be adjusted in a future commit.

This allows callers not to worry with md_info and makes it easier to
provide a PSA version for when MD_C is not available.

This will also make it easier to provide a PSA-based version for when MD

Some of them no longer need md_ctx, some of those no longer need the
exit dance that was used to free it, or need it on a smaller scope.

This is a first step towards making a version of this function that
uses PSA when MD is not available.

Looking at the bigger picture it is clear that if `ssl->session` is NULL,
there will be a failure much earlier, and that is well protected from,
however, the practice of dereferencing a pointer which has not been
verified in prior for validity goes against secure coding practices.
