Add dependencies on built-in hash of signature/
signature verification and asymmetric
encryption/decryption tests. The dependency is
not added for tests based on SHA-256 as SHA-256
is always present when PSA is involved (necessary
to the PSA core) and that way most of PSA signature
/verification tests are still run when PSA hash
operations are accelerated.

As PSA signatures rely on built-in hash implementations
(cannot take an advantage of an accelerator for the
time being), chose an available built-in hash for
tests exercising a signature key.

Add ECDSA and RSA signature acceleration testing
with signature capabilitites removed from the
Mbed TLS library.

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.

The current testing of the PSA configuration is
based on test code located in the library itself.
Remove this code as we are moving to using a
test library instead.

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.

PR #3959 has proven that by adding a prefix
(LIBTESTDRIVER1/libtestdriver1_ in this commit) to
all MBEDTLS/PSA_* and mbedtls/psa_* symbols of a copy
of the Mbed TLS library, we can build a library that
can be linked with the Mbed TLS library.
This commit leverages this to build a PSA test driver
library based on the Mbed TLS library code.
The cryptographic features supported by the test
library are defined by:
. a minimal configuration (in the sense of config.h),
see config_test_driver.h
. PSA_WANT_* and PSA_ACCEL_* defined macros.
The PSA_WANT_* macros have to be the same as the ones
used to build the Mbed TLS library the test driver
library is supposed to be linked to as the PSA_WANT_*
macros are used in the definition of structures and
macros that are shared by the PSA crypto core,
Mbed TLS drivers and the driver test library.
The PSA_ACCEL_* macros are intended to define the
cryptographic features that have to be removed
from the Mbed TLS library and thus supported by the
test library in test scenarios. The PSA_ACCEL_* macros
to build the test library are thus mirrored from the
ones to build the Mbed TLS library by extended the
crypto_config.h: see
crypto_config_test_driver_entension.h.

Rename test driver entry points to
libtestdriver1_<name of the Mbed TLS entry point>.
This aligns with the renaming of all Mbed TLS APIs
for the test driver library (that will be put in place
in the following commits) to avoid name conflicts
when linking it with the Mbed TLS library.

Define test driver entry points that provide an alternative
to Mbed TLS driver entry points only when the PSA configuration
is used. Their purpose is only to test the PSA configuration
thus there is no good reason to use them out of this scope.

The PSA max hash size has to be 64 if SHA512 or
SHA384 is supported by the library or an
accelerator, not just in case of the library.

The test entry points defined in psa_crypto_hash.c
and psa_crypto_mac.c are supposed to be exact
clones of the Mbed TLS driver entry points. Thus
the operation type should be the Mbed TLS operation
type not a test one. There was no compilation error
as the hash and cipher operation test types are
currently equal to the Mbed TLS ones.

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.

This slightly increases the RAM consumption per context, but saves code
size on architectures with an instruction for direct byte access (which is
most of them).
Although this is technically an API break, in practice, a realistic
application won't break: it would have had to bypass API functions and rely
on the field size (e.g. relying on -1 == 1 in a 1-bit field).
