Instead of using the legacy mbedtls_ecp_mul() function which makes use of
ECP's math, this commit adds a new function named pk_derive_public_key()
which implements the same behavior using PSA functions.
The flow is simple:
- import the private key into PSA
- export its public part

Instead of using the legacy mbedtls_ecp_check_pub_priv() function which
was based on ECP math, we add a new option named eckey_check_pair_psa()
which takes advantage of PSA.
Of course, this is available when MBEDTLS_USE_PSA_CRYPTO in enabled.
Tests were also fixed accordingly.

Now, that the errors are not silently ignored
anymore, instead of expecting a <malformed>
tag in parsed data, the test case returns
an error.

We keep tests without USE_PSA for single accel components (i.e.
ECDH, ECDSA, ECJPAKE), but when testing for all 3 accelerated
at the same time we use USE_PSA for better test coverage.
However for this purpose there is already the:
component_test_psa_crypto_config_[reference/accel]_all_ec_algs_use_psa()
so we can delete this extra component.

All these EC based algs are now tested all at once in
test_psa_crypto_config_[accel/reference]_all_ec_algs_use_psa()
functions.

Actually this adds both the accelerated test as well as the
reference. Both of them are used to evaluate the driver's
coverage with analyze_outcomes.py script.

TLS 1.2 has never been able to work with only SHA-512, it just happened
to pass previously because the declared dependencies were too lax.
(Probably related to the fact that in the past we didn't distinguish
between SHA-512 and SHA-384 in dependencies.)
So, just disable all of TLS in SHA-512-only builds. While at it, tune
build_info.h to make this easier - it already had partial support for
disabling TLS 1.2 or TLS 1.3 in an easier way, but not both of them at
the same time.

Now that Entropy doesn't need it any more, we can have driver-only
SHA-256 (and 224 with it) in the non-USE_PSA component too.
This reveals a missing PSA_INIT in a PK test using SHA-256.

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- documentation and historical documents: Changelog, docs/**/*.md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.

These were assuming that psa_crypto_init() doesn't call hashes, which is
not always correct.

Allow the script to also execute the tests needed for the following
analysis. It doesn't affect the previous usage of this script:
- if the output file is already present, then only the analysis
is performed
- if the outfile does not exists, then tests are also executed
before doing the analysis
