efb584d4c0 Add storage tests for lifetimes
Test keys with various persistence levels, enumerated from the
metadata tests.

For read-only keys, do not attempt to create or destroy the key
through the API, only to read a key that has been injected into
storage directly through filesystem access.

Do not test keys with a non-default location, since they require a
driver and we do not yet have a dependency mechanism to require the
presence of a driver for a specific location value.

30ccba48ef Do support multiple files generated from the same script
The call to `tests/scripts/generate_psa_tests.py` added by the commit
"generate_psa_tests.py: allow generating each file independently"
assumed that the `check` function supports multiple file names, but in
fact it does not do so. When `generate_psa_tests.py` started generating
more than one file, `check-generated-files.sh` did not detect changes to
files other than the first one listed by `generate_psa_tests.py --list`.

Fix this: change `check` to support either a single directory (with
detection of added/removed files) or a list of files (which is assumed
to be static).

b93f854f4c Expand psa_generate_tests to support constructor arguments
In macro_collector.py, base InputsForTest on PSAMacroEnumerator rather
than PSAMacroCollector. It didn't make much sense to use
PSAMacroCollector anymore since InputsForTest didn't use anything
other than the constructor.

psa_generate_tests now generates arguments for more macros.
In particular, it now collects macro arguments from
test_suite_psa_crypto_metadata. Algorithms with parameters are now
supported.

ae9f14b159 Speed up the generation of storage format test cases
First build a list of all keys, then construct all the corresponding
test cases. This allows all required information to be obtained in
one go, which is a significant performance gain as the information
includes numerical values obtained by compiling a C program.

d6d2d6a7d7 Use InputsForTest in generate_psa_tests
In generate_psa_tests, use InputsForTest rather than PSAMacroCollector
to gather values. This way, the enumeration of values to test includes
values used in metadata tests in addition to constructors parsed from
header files. This allows greater coverage of values built from
constructors with arguments. This doesn't make a difference yet, but
it will once algorithm constructors with arguments are supported in
generate_psa_tests.

Make the injection of numerical values optional. They are useful for
test_psa_constant_names, so keep them there. Don't use them for
not-supported tests: they might make sense, but the current code
wouldn't work since it doesn't know how to make up fake key material
or what dependencies to generate. Don't use them for storage tests:
they only make sense for supported values.

Don't inject 'PSA_SUCCESS': that's superfluous.

c17f29309f psa: Support RSA signature without MBEDTLS_GENPRIME
On space-constrained platforms, it is a useful configuration to be able
to import/export and perform RSA key pair operations, but to exclude RSA
key generation, potentially saving flash space. It is not possible to
express this with the PSA_WANT_ configuration system at the present
time. However, in previous versions of Mbed TLS (v2.24.0 and earlier) it
was possible to configure a software PSA implementation which was
capable of making RSA signatures but not capable of generating RSA keys.
To do this, one unset MBEDTLS_GENPRIME.

Since the addition of MBEDTLS_PSA_BUILTIN_KEY_TYPE_RSA_KEY_PAIR, this
expressivity was lost. Expressing that you wanted to work with RSA key
pairs forced you to include the ability to generate key pairs as well.

Change psa_crypto_rsa.c to only call mbedtls_rsa_gen_key() if
MBEDTLS_GENPRIME is also set. This restores the configuration behavior
present in Mbed TLS v2.24.0 and earlier versions.

It left as a future exercise to add the ability to PSA to be able to
express a desire for a software or accelerator configuration that
includes RSA key pair operations, like signature, but excludes key pair
generation.

Without this change, linker errors will occur when attempts to call,
which doesn't exist when MBEDTLS_GENPRIME is unset.
    psa_crypto_rsa.c.obj: in function `rsa_generate_key':
    psa_crypto_rsa.c:320: undefined reference to `mbedtls_rsa_gen_key'

Fixes #4512

897dff9527 Code to generate storage format test cases
Start generating storage format test cases. This commit introduces two test
data files: test_suite_psa_crypto_storage_format.v0.data for reading keys in
storage format version 0 (the current version at this time), and
test_suite_psa_crypto_storage_format.current.data for saving keys in the
current format (version 0 at this time).

This commit kicks off the test case generation with test cases to exercise
the encoding of usage flags. Subsequent commits will cover other aspects of
keys.

60b29fea46 Define WANT symbols for always-supported key types
PSA_KEY_TYPE_RAW_DATA and PSA_KEY_TYPE_DERIVE are always supported.
Make this explicit by declaring PSA_WANT_KEY_TYPE_RAW_DATA and
PSA_WANT_KEY_TYPE_DERIVE unconditionally. This makes it easier to
infer dependencies in a systematic way.

Don't generate not-supported test cases for those key types. They
would always be skipped, which is noise and would make it impossible
to eventually validate that all test cases pass in at least one
configuration over the whole CI.

Don't remove the exception in set_psa_test_dependencies.py for now, to
get less noise in dependencies. This may be revised later if it is
deemed more important to be systematic.

the fact that the generated file doesn't change). To keep things
