This saves ~160 bytes of code size, at the cost of a bit of localized
complexity in the code. The impact on performance is measurable but small
(<5% observed on x86_64) and can go either way (there's a calculation vs
memory bandwidth compromise).

Calling mbedtls_test_fail() attempts to lock the test data mutex.
Unfortunately we were calling this from places where we already held
this mutex, and this mutex is not recursive, so this deadlocks. Split
out mbedtls_test_fail() into mbedtls_test_fail_internal() in order to
address this.

This fixes the ability to exercise keys in configurations where MD5 is
supported for direct use, but not inside some accelerated algorithms. This
is the case in `all.sh test_psa_crypto_config_accel_ecc_ecp_light_only` and
some other accelerated-ECC components of `all.sh`, where the driver is built
without MD5 support but built-in MD5 remains enabled.
This is only a hack, not a theoretically correct fix, but a correct fix is
out of scope of my current work.

Parsing a key and importing it into PSA may result in a policy that
specifies an algorithm that is not included in the build. This happens if
the key type is supported, but not the algorithm, e.g. in a build with
MBEDTLS_ECP_C but not MBEDTLS_ECDSA_C.

In some configurations (e.g. ECDH but no ECDSA or RSA), the PK module is
useful but cannot perform any signatures. Then modern GCC complains:
```
../source/tests/suites/test_suite_pk.function: In function ‘test_pk_sign_verify’:
../source/tests/suites/test_suite_pk.function:1136:12: error: array subscript 0 is outside array bounds of ‘unsigned char[0]’ [-Werror=array-bounds]
../source/tests/suites/test_suite_pk.function:1094:19: note: while referencing sig’
…
```
This fixes test-ref-configs.pl with a modern GCC (specifically with
config-thread.h).

Set unique configuration names in the outcome file. This was lost in the
rewrite from depends-*.pl to depends.py.

Implement mbedtls_pk_import_into_psa for all PK types except RSA_ALT.
This covers importing a key pair, importing a public key and importing
the public part of a key pair.
Test mbedtls_pk_import_into_psa() with the output of
mbedtls_pk_get_psa_attributes(). Also unit-test mbedtls_pk_import_into_psa()
on its own to get extra coverage, mostly for negative cases.

There was already code to instantiate the wildcard for sign/verify-hash.
Make that work with sign/verify-message as well.

Do for public keys what
"Fix mbedtls_pk_get_bitlen() for RSA with non-byte-aligned sizes"
did for key pairs.

Add non-regression tests. Update some test functions to not assume that
byte_length == bit_length / 8.
