We were testing the internal consistency of the resulting key, and that the
resulting key had the right metadata, but we were not testing that the PSA
key had the expected key material. Comparing the public keys fixes that.

In TLS 1.3 early data tests, to reduce the risk
of not updating a switch over possible scenarios
when adding a new scenario, add systematically a
default case that fails the test.

This was only tested with opaque keys. Since the code paths are different
depending on the PK type, we also need to test RSA and ECKEY.

Custom-e RSA key generation is not yet supported in the test driver, and we
don't support fallback from the test driver to the built-in
implementation (even though we're testing with MBEDTLS_RSA_C). So for the
time being, only run psa_generate_key_ext test cases for RSA with a custom
public exponent when using the built-in implementation.
Add a test case to validate that psa_generate_key_ext test cases for RSA
with a custom public exponent returns NOT_SUPPORTED (rather than silently
doing the wrong thing) when not using built-in RSA (which is subtly
different from when having accelerated RSA: if both are enabled, which we
currently don't do in all.sh, then this should be supported and this is
validated by the test cases above).
This wart will be resolved when we add support for drivers with a
generate_key_ext entry point.

Instead of passing the size of the whole structure, just pass the data
length and let the implementation worry about adding the size of the
structure. The intent with passing the structure size was to allow
the client code in a client-server implementation to know nothing
about the structure and just copy the bytes to the server. But that was not
really a useful consideration since the application has to know the
structure layout, so it has to be available in the client implementation's
headers. Passing the method data length makes life simpler for everyone by
not having to worry about possible padding at the end of the structure, and
removes a potential error condition
(method_length < sizeof(psa_key_generation_method_t)).

In valid_parameters_pkwrite, we first parse a public key then test
with mbedtls_pk_write_xxx functions. So valid_parameters_pkwrite
should depend on both MBEDTLS_PK_WRITE_C and MBEDTLS_PK_PARSE_C.

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).

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.
