a1ce2f2675 Rename test driver lifetime to location
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.

1a0fbacde1 Refactor opaque key handling in the test driver
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.

2385f71abd Fix and simplify test assertions
mbedtls_test_fail does not copy the failure explanation string, so
passing a string on the stack doesn't work. This fixes a garbage
message that would appear if a test triggered a non-implemented code
path.

More generally, just use TEST_ASSERT instead of explicitly calling
mbedtls_test_fail, since we aren't playing any tricks with the error
location.

2fa6b5f503 ECC import: more useful choice of INVALID_ARGUMENT vs NOT_SUPPORTED
Attempting to create an ECC key with a curve specification that is not
valid can plausibly fail with PSA_ERROR_INVALID_ARGUMENT ("this is not
a curve specification at all") or PSA_ERROR_NOT_SUPPORTED ("this may
be a curve specification, but not one I support"). The choice of error
is somewhat subjective.

Before this commit, due to happenstance in the implementation, an
attempt to use a curve that is declared in the PSA API but not
implemented in Mbed TLS returned PSA_ERROR_INVALID_ARGUMENT, whereas
an attempt to use a curve that Mbed TLS supports but for which support
was disabled at compile-time returned PSA_ERROR_NOT_SUPPORTED. This
inconsistency made it difficult to write negative tests that could
work whether the curve is implemented via Mbed TLS code or via a
driver.

After this commit, any attempt to use parameters that are not
recognized fails with NOT_SUPPORTED, whether a curve with the
specified size might plausibly exist or not, because "might plausibly
exist" is not something Mbed TLS can determine.

To keep returning INVALID_ARGUMENT when importing an ECC key with an
explicit "bits" attribute that is inconsistent with the size of the
key material, this commit changes the way mbedtls_ecc_group_of_psa()
works: it now works on a size in bits rather than bytes, with an extra
flag indicating whether the bit-size must be exact or not.

1af872d23b Move the fake PSA external RNG to its own header and source files
Move the declaration of the functions needed to use the test
implementation of mbedtls_psa_external_get_random() to a new header
file. Before, they were declared in
tests/include/test/psa_crypto_helpers.h, but this header file can't be
included in sample programs because it also includes headers from the
library directory which is not on the include path for sample
programs.

This fixes the build of the sample programs when
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_USE_PSA_CRYPTO are
enabled.

Move the implementation of the functions to a separate .c file as
well. This isn't strictly necessary, but makes the structure of the
source code easier to understand.
