Since we have removed PK_C, PK_[WRITE/PARSE]_C, there is no need to
define PK related configurations again. Therefore we removed them
in common_tfm_config to make a simpler.

This commit adds dependency check when PK_CAN_ECDSA_SIGN or
PK_CAN_ECDSA_VERIFY is enabled but no corresponding ASN1_WRITE_C
or ASN1_PARSE_C is enabled under PSA.

We have set MBEDTLS_MD_C in tfm_mbedcrypto_config_profile_medium.h
so there is no need to enable it again.

config-tfm.h is copied into mbedtls_config.h in test-ref-config.pl.
The relative path is include/ not configs/.

This is what TF-M intended and they have done so since we copied the file.
It's either disable these options, or enable MBEDTLS_OID_C.

When testing the lifecycle of a transient key, it doesn't make much sense to
try psa_open_key: that expects a persistent key and the lookup takes a
different path. The error from psa_open_key is also different depending on
whether MBEDTLS_PSA_CRYPTO_STORAGE_C is enabled.
To check that the key ownership is taken into account, try to access the
same key id with a different owner without expecting that this is a
persistent key. Just call psa_get_key_attributes, which works fine for a
transient key.
This fixes a test failure when MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER is
enabled and MBEDTLS_PSA_CRYPTO_STORAGE_C is disabled.

Separate the fits-in-buffer check (*data_length <= data_size) from the
we-think-it's-a-sensible-size check (*data_length <=
MBEDTLS_X509_MAX_DN_NAME_SIZE).
This requires using an intermediate buffer for the DER data, since its
maximum sensible size has to be larger than the maximum sensible size for
the payload, due to the overhead of the ASN.1 tag+length.
Remove test cases focusing on the DER length since the implementation no
longer has a threshold for it.

Fix the expected output in some test cases.
Add a few more test cases to exercise both a payload length around 256 bytes
and a DER length around 256 bytes, since both are placed in a 256-byte
buffer (value of MBEDTLS_X509_MAX_DN_NAME_SIZE).

Due to differing validations amongst X.509 library functions, there are
inputs that mbedtls_x509_string_to_names() accepts, but it produces output
that some library functions can't parse. Accept this for now. Do call the
functions, even when we don't care about their return code: we're ok with
returning errors, but not with e.g. a buffer overflow.

Rename the function from parse_attribute_value_der_encoded: the hex aspect
seems important.
There was a buffer overflow due to not validating that the intermediate data
fit in the stack buffer. The rewrite doesn't use this buffer, and takes care
not to overflow the buffer that it does use.
Document all that's going on.

In particular, "X509 String to Names: long hexstring (DER=258 bytes, too long)"
causes a buffer overflow in parse_attribute_value_der_encoded().
