Note that ECC key derivation is not using drivers yet, as we don't have driver support for
cooked key derivation acceleration, see

The test driver library tries to only build what's necessary, but must
use the same PSA_WANT macros as the main library. So, for things that
are not needed, it undefines MBEDTLS_PSA_BUILTIN_xxx and defines
MBEDTLS_PSA_ACCEL_xxx, unless the ACCEL symbol was defined on the
command line, in which case it undefines it and defineds BUILTIN
instead. This negation happens in crypto_config_test_driver_extension.h
and reflects the fact that what we want accelerated in the main library
is what we want built-in in the driver library (and vice versa if we
want to minimize the size of the driver library).
So, the ACCEL symbols in inside the test driver library (while it's
being built, not those on the command line) are a bit of a white lie:
they don't actually mean "there's an accelerator for this" but instead
"I won't include a built-in for this even though the corresponding
PSA_WANT symbol is defined".
This was quite harmless until MD started making dispatch decisions based
on the ACCEL symbols: when it tries to dispatch to an accelerator that
doesn't actually exist, things tend to go badly.
The minimal fix for this is to change how we enable extra hashes in the
test driver library: by defining the ACCEL symbol on the command line,
in the build we'll end up with the BUILTIN symbol (and implementation!)
and no ACCEL symbol, which is exactly what we want.

Regarding testing, the no_md component was never very useful, as that's
not something people are likely to want to do: it was mostly useful as
executable documentation of what depends on MD. It's going to be even
less useful when more and more modules auto-enable MD_LIGHT or even
MD_C. So, recycle it to test the build with only MD_LIGHT, which is
something that might happen in practice, and is necessary to ensure that

In the python script I didn't use the word TODO because pylint doesn't
like that, but morally it's the same.
I removed the comment about "do we need a subset of compat.sh?" because
it turns out that `ssl-opt.sh` is already exercising all the key
exchanges:
% sed -n 's/.*force_ciphersuite=TLS-\([^ ]*\)-WITH.*/\1/p' tests/ssl-opt.sh | sort -u
DHE-PSK
DHE-RSA
ECDH-ECDSA
ECDHE-ECDSA
ECDHE-PSK
ECDHE-RSA
ECJPAKE
PSK

RSA-PSK
(the only omission is ECDH-RSA which is not of interest here and does
not actually differ from ECDH-ECDSA). So, we don't need a subset of
compat.sh because we're already getting enough testing from ssl-opt.sh
(not to mention test_suite_ssl).

These variables were both uses to select the default version of OpenSSL
to use for tests:
- when running compat.sh or ssl-opt.sh directly, OPENSSL_CMD was used;
- when running all.sh, OPENSSL was used.
This caused surprising situations if you had one but not the other set
in your environment. For example I used to have OPENSSL_CMD set but not
OPENSSL, so ssl-opt.sh was failing in some all.sh components but passing
when I ran it manually in the same configuration and build, a rather
unpleasant experience.
The natural name would be OPENSSL, and that's what set in the Docker
images used by the CI. However back in the 1.3.x days, that name was
already used in library/Makefile, so it was preferable to pick a
different one, hence OPENSSL_CMD. However the build system has not been
using this name since at least Mbed TLS 2.0.0, so it's now free for use
again (as demonstrated by the fact that it's been set in the CI without
causing any trouble).
So, unify things and use OPENSSL everywhere. Just leave an error message
for the benefit of developers which might have OPENSSL_CMD, not OPENSSL,
set in their environment from the old days.

The script was parsing the output from `make lcov` to extract numbers and

This is more robust than the previous code, which relied on `tail -n4` to
extract relevant lines, which broke when `make lcov` started to emit one
