Ronald Cron 80eaa93b59 tests: psa: Reactivate and expand key management through test driver
The compilation guards in key_management.c are now
accelerator compilation guards (MBEDTLS_PSA_ACCEL_KEY_TYPE_xyz).

As a consequence when running the PSA driver wrapper
tests as part of test_psa_crypto_config_basic
and test_psa_crypto_drivers all.sh components all
key management cryptographic operations were handled by
the software builtin fallback, and not by the test driver
as intended in the first place.

This commits fixes this issue by:
. declaring an accelerator for ECC key pairs in
  test_psa_crypto_config_basic.
. declaring an accelerator for both ECC and RSA
  key pairs in test_psa_crypto_drivers.

It is possible to declare an accelerator for both
ECC and RSA key pairs in test_psa_crypto_drivers
and not in test_psa_crypto_config_basic because
in the case of test_psa_crypto_drivers the new
PSA configuration is not activated. That way,
the builtin fallback software implementation
is present to supply the transparent test driver
when some support is missing in it (mainly
RSA key generation).

Note that the declaration of accelerators does
much more than just "fixing" the execution flow of
driver wrapper tests, it makes all import and public
key export cryptographic operations in all unit
tests being handled by the transparent test driver
(provided that it supports the key type).

One test case related to key generation is
partially disabled. This will be fixed with the
rework of psa_generate_key along the lines
described in psa-crypto-implementation-structure.md.

Ronald Cron ea0f8a6d1a psa: se: Create key context in SE key slots
In key slots containing the description of a key of a
dynamically registered Secure Element (SE), store the
key slot number in a key context as defined in the
PSA driver interface for opaque drivers.

That way transparent key data and slot numbers are
, in a key slot, both stored in a dynamically allocated
buffer. The `data` union in structures of type
psa_key_slot_t to distinguish between the storage of
transparent key data and slot numbers is consequently
not necessary anymore and thus removed.

This alignement of some part of the code dedicated to
dynamically registered SE with the PSA driver interface
specification is done to ease the support of both
dynamically registered and statically defined secure
elements.

Gilles Peskine 72d8e0ad04 Key policy negative tests don't actually require the algorithm
It doesn't make much difference in practice, but to keep closer to
what the current code does, run negative key policy tests even if the
algorithm for the operation attempt is not supported.

In particular, this allows the following test cases to run:
* "PSA key policy: agreement + KDF, wrong agreement algorithm"
* "PSA key policy: raw agreement, wrong algorithm"
Without this exception, those two test cases would never run, because
they would depend on PSA_ALG_WANT_FFDH. Since FFDH is not implemented
yet, it isn't enabled in any configuration. There's no alternative to
FFDH for these particular test cases because ECDH is the only key
agreement that is implemented in Mbed TLS so far.

Gilles Peskine 20987b9a46 Detect test cases that require something not to be supported
PSA_xxx_CATEGORY_yyy is used in metadata tests where it doesn't
involve any particular support, and elsewhere it's used as a value
that is definitely not supported but is in a plausible range. Such
symbols do not require any dependency.

If a test case is expects PSA_ERROR_NOT_SUPPORTED, its
dependencies (often including one negative dependency) cannot be
determined automatically, so leave that test case alone.

Gilles Peskine f032fa9d94 Special handling for some always-on or alias symbols
Some symbols don't require a dependency symbol:

* Modifiers such as truncated MAC
* Always-on features such as the raw data key type
* Aliases or special values such as RSA PKCS#1v1.5 raw

I'm not convinced that all of these warrant special handling in the
script, rather than having the expected symbol defined somewhere. But
for now I prefer to minimize changes to the header files.
