When PSA uses CTR_DRBG for its random generator and CTR_DRBG uses PSA for
AES, as currently implemented, there is one volatile key in permanent use
for the CTR_DRBG instance. Account for that in tests that want to know
exactly how many volatile keys are in use, or how many volatile keys can be
created.

When the PSA RNG uses AES through a PSA driver, it consumes one volatile key
identifier. When MBEDTLS_PSA_KEY_SLOT_DYNAMIC is enabled, that identifier
happens to coincide with the key ID value that the test case assumes not to
exist. Use a different value that avoids this coincidence.

Split the "many transient keys" test function in two: one that expects to
successfully create many keys, and one that expects to fill the key store.
This will make things easier when we add a dynamic key store where filling
the key store is not practical unless artificially limited.

PSA_KEY_ID_VOLATILE_MIN-1 is now in the persistent key ID range, so it's no
longer an invalid key ID for registration.

Restricting the built-in key range would be an API break since applications
can hard-code a built-in key value and expect that it won't clash with
anything else. Make it harder to accidentally break the API.

mbedtls_psa_register_se_key() is not usable with volatile keys, since there
is no way to return the implementation-chosen key identifier which would be
needed to use the key. Document this limitation. Reject an attempt to create
such an unusable key. Fixes#9253.

Make it possible, but not officially supported, to switch the CTR_DRBG
module to PSA mode even if MBEDTLS_AES_C is defined. This is not really
useful in practice, but is convenient to test the PSA mode without setting
up drivers.

Move the DATA_FILES_PATH_VAR variable into the generated bash rather
than only variablising it in the python that generates the test script.

A path containing '../../' was defined in relation to a directory in the
tests/data_files directory. Since this has been moved to
framework/data_files, we must update the path to refer correctly to the
same location as before.

The driver-vs-reference checks compare test results in different
configurations. Ignore the test results that report differences in
configurations that were the point of the comparison. Do compare other
configuration reports: this will let us know if the configurations diverge
in an unexpected way.

Generate option-on and option-off cases for test_suite_config, for all
boolean options (MBEDTLS_xxx and PSA_WANT_xxx, collected from the mbedtls
and PSA config files).

Add a test suite intended to report configuration options in the outcome
file: we're only interested in SKIP vs PASS.
Add a few test cases for some interesting combinations of options. The
selection here is just for illustration purposes, more will be added later.
A subsequent commit will automatically generate test cases for single options.

Alert if all tests are filtered out or skipped: that probably indicates a
test script that set up an unintended configuration or an overly strict
filter. You can pass `--min 0` to bypass this check. You can pass `--min`
with a larger value to require that many test cases to run.

On the CI, the git version when running on
Ubuntu 16.04 is 2.7 and it does not support
the "--recurse-submodules" option of
"git ls-files" thus do not use it.
Another argument to not use it is that
when TF-PSA-Crypto will be a submodule of
mbedtls we will not want check_files.py to
check the TF-PSA-Crypto files as well.
