check_pair() is not supported by opaque RSA keys, but we want
to be sure that calling this functions fails nicely instead
for crashing.

If the wrapped key has a PKCS1 v1.5 signature algorithm, then try
to call sign_ext() to perform PSA RSS. Of course this will fail
because it's not supported by the wrapped key.

If the public key is exported with mbedtls_pk_write_pubkey_der()
it should be re-imported with mbedtls_pk_parse_public_key().
Alternative options (when PK_WRITE is not defined), i.e.
mbedtls_ecp_point_write_binary() and mbedtls_rsa_write_pubkey(),
export the key in a different format which cannot be parsed by
pk_parse module so mbedtls_ecp_point_read_binary() and
mbedtls_rsa_parse_pubkey() should be used respectively in this
case.

Use mbedtls_test_key_consistency_psa_pk() to verify that the
generated PK contexts match with the original PSA keys instead
of doing sign/verify and encrypt/decrypt.

This bug was not found until now because:
- !PK_[WRITE|PARSE]_C is only tested in component_full_no_pkparse_pkwrite()
- the test only case concerning RSA key had MBEDTLS_PK_WRITE_C as dependency
so it was not executed in that component.

The behavior of the functions is kept intact. Changes concern:
- generate the initial PK context using PSA parameters only; this
allows to remove 1 input parameter for the test function.
- add/fix comments.

Try to perform verify_ext() using the opaque context when the
key type is MBEDTLS_PK_RSASSA_PSS. This currently leads to a
crash while running the test suite and this will be fixed by
the next commit.

Test the behavior of mbedtls_pk_get_psa_attributes() and
mbedtls_pk_import_into_psa() with respect to lifetime. In particular, test
that they work with persistent keys as documented.
Test cases generated by the following script:
```
for old in [('transparent', '0:0:1'),
('opaque volatile [export]', '1:0:1'),
('opaque volatile [copy]', '1:0:0'),
('opaque persistent [export]', '1:1:1'),
('opaque persistent [copy]', '1:1:0')]:
for to_public in [('pair', '0'),
('public', '1')]:
for to_persistent in [('volatile', '0'),
('persistent', '1')]:
depends = ('\ndepends_on:MBEDTLS_USE_PSA_CRYPTO'
if old[0].startswith('opaque')
else '')
print(f"""\
PSA import into PSA: {old[0]} -> {to_persistent[0]} {to_public[0]}{depends}
pk_import_into_psa_lifetime:{old[1]}:{to_public[1]}:{to_persistent[1]}
""")

Eventually we do not support early data with
external PSK thus no point to do a positive
test on that basis.
