The accessor macros for key_id and owner_id in the mbedtls_svc_key_id_t
need to have the MBEDTLS_PRIVATE() specifier as these fields are private

The cipher module implements XTS, and the PSA API specifies XTS, but the PSA
implementation does not support XTS. It requires double-size keys, which
psa_crypto does not currently support.

Use PSA_BUILTIN macros instead of the Mbed TLS ones
as in the hash operation contexts the context for a
given hash is needed only if the support for it
through PSA is enabled.

This commit removes the test_psa_crypto_config_basic
all.sh component that can no longer work without
adapting it to the separately compiled test driver
library. This component is replaced by several
components in the following commits to test various
type of acceleration independently.

static function mbedtls_set_key_owner() is declared in psa/crypto.h
and defined in psa/crypto_struct.h with different parameter name for
the mbedtls_key_owner_id_t parameter and that may trigger errors
from static code analysis tool as cppcheck.

Move fields around to have fewer accesses outside the 128-element Thumb
direct access window.
In psa_hkdf_key_derivation_t, move the large fields (output_block, prk,
hmac) after the state bit-fields. Experimentally, it's slightly better
to put hmac last.
Other operations structures don't go outside the window, at least when not
considering nested structures.

Several files among include/psa/crypto_*.h are not meant to be included
directly, and are not guaranteed to be valid if included directly. This
makes it harder to perform some static analyses. So make these files more
self-contained so that at least, if included on their own, there is no
missing macro or type definition (excluding the deliberate use of forward
declarations of structs and unions).

The current definition of PSA_ALG_IS_HASH_AND_SIGN includes
PSA_ALG_RSA_PKCS1V15_SIGN_RAW and PSA_ALG_ECDSA_ANY, which don't strictly
follow the hash-and-sign paradigm: the algorithm does not encode a hash
algorithm that is applied prior to the signature step. The definition in
fact encompasses what can be used with psa_sign_hash/psa_verify_hash, so
it's the correct definition for PSA_ALG_IS_SIGN_HASH. Therefore this commit
moves definition of PSA_ALG_IS_HASH_AND_SIGN to PSA_ALG_IS_SIGN_HASH, and
replace the definition of PSA_ALG_IS_HASH_AND_SIGN by a correct one (based
on PSA_ALG_IS_SIGN_HASH, excluding the algorithms where the pre-signature
step isn't to apply the hash encoded in the algorithm).
In the definition of PSA_ALG_SIGN_GET_HASH, keep the condition for a nonzero
output to be PSA_ALG_IS_HASH_AND_SIGN.
Everywhere else in the code base (definition of PSA_ALG_IS_SIGN_MESSAGE, and
every use of PSA_ALG_IS_HASH_AND_SIGN outside of crypto_values.h), we meant
PSA_ALG_IS_SIGN_HASH where we wrote PSA_ALG_IS_HASH_AND_SIGN, so do a
global replacement.

This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.
In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).
Changes in this commit:
* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
generate_psa_constant_names).

If PSA_CIPHER_ENCRYPT_OUTPUT_SIZE was called on a non symmetric key,
then a divide by zero could happen, as PSA_CIPHER_BLOCK_LENGTH will
return 0 for such a key, and PSA_ROUND_UP_TO_MULTIPLE will divide by the
block length.
