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.

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.

When TEST_EQUAL fails, show the two numerical values in the test log (only
with host_test). The values are printed in hexa and signed decimal.
The arguments of TEST_EQUAL must now be integers, not pointers or floats.
The current implementation requires them to fit in unsigned long long
Signed values no larger than long long will work too. The implementation
uses unsigned long long rather than uintmax_t to reduce portability
concerns. The snprintf function must support "%llx" and "%lld".
For this purpose, add room for two lines of text to the mbedtls_test_info
structure. This adds 154 bytes of global data.

If a fallback is not explicitly configured in the
mbedtls_test_rnd_buf_info structure, fail after the buffer is
exhausted.
There is no intended behavior change in this commit: all existing uses
of mbedtls_test_rnd_buffer_rand() have been updated to set
mbedtls_test_rnd_std_rand as the fallback.

Move the key buffer size calculation code under
tests to avoid check-names.sh to complain about
"likely macros with typos".
This removes the calculation of key buffer
sizes for the test driver from the wrapper based on
static size data. But the code is still there in test
code to be used when we go back to work on the
generation of the driver wrapper.

The macro always meant 'location', but was mistakenly named 'lifetime'.
Naming it location instead makes much more sense, and drives home the
conceptual differences between location and lifetime values.

Builtin key support for the test driver is always compiled in, and no
longer guarded by MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS.
Parsing the key slot from the buffer by cast and assign instead of memcmp.
For exporting keys, the test driver no longer reaches into the key
identifier in order to check whether a key is builtin, but rather
assumes so based on the key buffer length. It's the driver's
responsibility to be able to detect the key material it returned as part
of the get_builtin_key operation.

`error.c` is a file generated from `error.h` and thus cannot contain the code
that was previously added. This commit fixes that issue by moving the
`MBEDTLS_ERR_ADD` macro and associated function and function pointer into
`common.h` and `common.c`.
Also fix a typo in `tests/include/test/helpers.h` where tabs were accidentally
used instead of spaces.

Adds a macro (`MBEDTLS_ERR_ADD`) to add error codes together and check that the
result will not be corrupted. This additional check is only enabled during
testing when `MBEDTLS_TEST_HOOKS` is defined.
Also includes a reference usage example in `rsa.c` where two high-level error
codes could be incorrectly added together under the right conditions. This now
ensures that when this error occurs during testing it will be correctly
reported.

ARRAY_LENGTH has a portable but unsafe implementation, and a
non-portable implementation that causes a compile-time error if the
macro is accidentally used on a pointer.
The safety check was only implemented for __GCC__-defining compilers,
but the part that triggered the compile-time error was always used. It
turns out that this part triggers a build warning with MSVC (at least
with some versions: observed with Visual Studio 2013).
```
C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\tests\src\psa_crypto_helpers.c(52): error C2220: warning treated as error - no 'object' file generated [C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\mbedtls_test.vcxproj]

```
Since a compile-time error is never triggered when the compile-time
check for the argument type is not implemented, just use the unsafe
macro directly when there's no safety check.

This ensures that test cases won't leave persistent files behind even
on failure, provided they use TEST_USES_KEY_ID(). Test cases that
don't use this macro are unaffected.
Tests that use PSA_DONE() midway and expect persistent keys to survive
must use PSA_SESSION_DONE() instead.
