Test the exact output from known RNG input. This is overly
constraining, but ensures that the code has good properties.

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.

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).

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.

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.

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.

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.

The test "PSA generate key: RSA, 1024 bits, good, encrypt (OAEP
SHA-256)" had a dependency on MBEDTLS_GENPRIME, but this was not listed
in the dependencies. Add MBEDTLS_GENPRIME to the test's dependencies to
ensure it has what it needs to run.

CI was failing on check_params due to

Re-create a component check_generated_files. Unlike the old one, which checked
that the generated files were up-to-date, the job of the new one is to check
that tests/scripts/check-generated-files.sh works (at least to the extent of
not errorring out).

Ensure that the .c files that generate_visualc_files.pl enumerates are present
before it runs. Otherwise, depending on the order in which make builds
targets, running `make generated_files` from a fresh checkout could end up
missing `library/error.c` and `library/version_features.c`.

Don't regenerate configuration-independent files when config.h or
crypto_config.h changes. These files only depend on the set of symbols
present in the headers and not on which symbols are enabled. To avoid
rebuilding the generated files whenever the configuration changes,
don't declare the configuration as a dependency.
In the rare event that a maintainer makes an edit to *config.h that
affects the generated files, they'll have to remove the generated files.
