The test framework stores size_t and int32_t values in the parameter store
by converting them all to int. This is ok in practice, since we assume int
covers int32_t and we don't have test data larger than 2GB. But it's
confusing and error-prone. So make the parameter store a union, which allows
size_t values not to be potentially truncated and makes the code a little
clearer.

Unless I missed something, all remaining instance of all macros are in
files where it makes sense to use these. I went over the output of:
git grep -c -E 'MBEDTLS_(MD5|RIPEMD160|SHA[0-9]*)_C'
and I think all the files listed fall into one of the following
acceptable categories:
- documentation and historical documents: Changelog, docs/**/*.md
- config files and related: mbedtls_config.h, configs/*.h,
check_config.h, config_psa.h, etc.
- scripts that build/modify configs: all.sh, depends.py,
set_psa_test_dependencies.py, etc.
- implementation of MD or PSA or related: md.h, psa_util.h, etc. and
corresponding test suites
- implementation of hashes: md5.c, sha256.h, etc. and corresponding test
suites
- two example programs using a low-level hash API: hash/hello.c,
pkey/ecdsa.c
- test/benchmark.c, test/selftest.c: actually want our built-in
implementations
- a function in test_suite_psa_crypto_storage_format that is
specifically for checking if the hash is built in.

We only enable SHA-256, so let's use that.
Previously the entropy module was deciding which hash to use based on
MBEDTLS_xxx_C feature macros, and since only SHA256_C was defined in
config_test_driver.h, it used that and things worked.
However since entropy was changed to use MD light, and
MBEDTLS_MD_CAN_xxx feature macros, we had an issue: when building
libtestdriver1 with its default config, MBEDTLS_PSA_ACCEL_ALG_SHA_512 is
defined even though there's no actual accelerator in the build. (This is
done so that PSA_WANT_ALG_SHA_512 can remain defined in order to match
the application's config, while not defining
MBEDTLS_PSA_BUILTIN_ALG_SHA_512 in order to only include what we need in
the build of libtestdriver1.) This will cause MD to dispatch to PSA in
order to take advantage of the accelerator, which will then fail because
there is no accelerator not builtin for this hash.
In the long-term, perhaps it would be best to address the root of the
issue: defining MBEDTLS_PSA_ACCEL_ALG_SHA_512 in a build that doesn't
actually have a SHA-512 accelerator is a lie. But that would require
significant changes in libtestdriver1. So for now, just fix the most
obvious symptom (picking a non-supported hash in entropy.h) by forcing
the choice of hash to match what's in the libtestdriver1 config.
Note: if the copy of entropy module in libtestdriver1 doesn't work,
we'll get a failure when calling libtestdriver1_psa_crypto_init(), which
we do, from mbedtls_test_transparent_init(), indirectly called by our
psa_crypto_init() which will then fail.

- Add `alg` and `computation_stage` to `psa_pake_operation_s`.
Now when logic is moved to core information about `alg` is required.
`computation_stage` is a structure that provides a union of computation stages for pake algorithms.
- Move the jpake operation logic from driver to core. This requires changing driver entry points for `psa_pake_output`/`psa_pake_input` functions and adding a `computation_stage` parameter. I'm not sure if this solution is correct. Now the driver can check the current computation stage and perform some action. For jpake drivers `step` parameter is now not used, but I think it needs to stay as it might be needed for other pake algorithms.
- Removed test that seems to be redundant as we can't be sure that operation is aborted after failure.

Move bignum-related helper functions to their own files under tests/include

include <test/helpers.h> without having the library directory on the include
path (we do this in some programs under programs/ intended for testing).

When testing under Valgrind for constant flow, skip test suites that don't
have any constant-flow annotations, since the testing wouldn't do anything
more that testing with ordinary Valgrind (component_test_valgrind and
component_test_valgrind_psa). This is a significant time saving since
testing with Valgrind is very slow.

The bignum module does not officially support "negative zero" (an
mbedtls_mpi object with s=-1 and all limbs zero). However, we have a
history of bugs where a function that should produce an official
zero (with s=1), produces a negative zero in some circumstances. So it's
good to check that the bignum functions are robust when passed a negative
zero as input. And for that, we need a way to construct a negative zero
from test case arguments.
There are checks that functions don't produce negative zeros as output in
the test suite. Skip those checks if there's a negative zero input: we
don't want functions to _create_ negative zeros, but we don't mind if
they _propagate_ negative zeros.

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

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.
