3a4f0e3cc4 tests: psa: Reset key attributes where needed
After a call to psa_get_key_attributes() to retrieve
the attributes of a key into a psa_key_attributes_t
structure, a call to psa_reset_key_attributes() is
mandated to free the resources that may be
referenced by the psa_key_attributes_t structure.
Not calling psa_reset_key_attributes() may result in
a memory leak.

When a test function calls psa_get_key_parameters()
the associated key attributes are systematically
reset in the clean-up part of the function with a
comment to emphasize the need for the reset and make
it more visible.

71016a9ea7 psa: Rename psa_key_file_id_t to mbedtls_svc_key_id_t
With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.

The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.

The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.

As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
  MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT
. PSA_KEY_FILE_GET_KEY_ID to MBEDTLS_SVC_KEY_ID_GET_KEY_ID
. psa_key_file_id_make to mbedtls_svc_key_id_make

27238fcbd8 psa: Use psa_key_file_id_t as the key id type
The purpose of this commit and the following is for
psa_key_id_t to always be as defined by the PSA
Cryptography API specification.

Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.

Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.

It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.

As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.

By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

090e16cb8b Don't destroy the key during a MAC verification operation
An early draft of the PSA crypto specification required multipart
operations to keep working after destroying the key. This is no longer
the case: instead, now, operations are guaranteed to fail. Mbed TLS
does not comply yet, and still allows the operation to keep going.
Stop testing Mbed TLS's non-compliant behavior.

02c78b7825 tests: Create an include folder
Create an include folder dedicated to include files for
tests. With the upcoming work on tests for PSA crypto
drivers the number of includes specific to tests is going
to increase significantly thus create a dedicated folder.

Don't put the include files in the include folder but in
include/test folder. This way test headers can be included
using a test/* path pattern as mbedtls and psa headers
are included using an mbedtls/* and psa/* path pattern.
This makes explicit the scope of the test headers.

Move the existing includes for tests into include/test and
update the code and build systems (make and cmake)
accordingly.
