It doesn't make much difference in practice, but to keep closer to
what the current code does, run negative key policy tests even if the
algorithm for the operation attempt is not supported.
In particular, this allows the following test cases to run:
* "PSA key policy: agreement + KDF, wrong agreement algorithm"
* "PSA key policy: raw agreement, wrong algorithm"
Without this exception, those two test cases would never run, because
they would depend on PSA_ALG_WANT_FFDH. Since FFDH is not implemented
yet, it isn't enabled in any configuration. There's no alternative to
FFDH for these particular test cases because ECDH is the only key
agreement that is implemented in Mbed TLS so far.

PSA_xxx_CATEGORY_yyy is used in metadata tests where it doesn't
involve any particular support, and elsewhere it's used as a value
that is definitely not supported but is in a plausible range. Such
symbols do not require any dependency.
If a test case is expects PSA_ERROR_NOT_SUPPORTED, its
dependencies (often including one negative dependency) cannot be
determined automatically, so leave that test case alone.

Some symbols don't require a dependency symbol:
* Modifiers such as truncated MAC
* Always-on features such as the raw data key type
* Aliases or special values such as RSA PKCS#1v1.5 raw
I'm not convinced that all of these warrant special handling in the
script, rather than having the expected symbol defined somewhere. But
for now I prefer to minimize changes to the header files.

Don't remove cipher-related dependencies because the corresponding
PSA_WANT_xxx dependencies are not implemented yet.

Remove any existing PSA_WANT_xxx dependency. Add PSA_WANT_xxx
dependencies based on the PSA_KEY_TYPE_xxx and PSA_ALG_xxx symbols
used in the test case arguments.
PSA_ECC_FAMILY_xxx and PSA_DH_GROUP_xxx are not implemented yet in the
PSA conditional inclusion mechanism in Mbed TLS, so this script
doesn't handle them yet.

Parse the existing dependencies. For now, just write them back.
Subsequent commits will implement the dependency processing that is
the goal of this program.

This commit only contains a framework to rewrite .data files. No
actual modification of the content is implemented yet.
For now, command line parsing is trivial: just a list of file names,
with no options.

When using the test function persistent_key_load_key_from_storage with
DERIVE_KEY, there's a dependency on HKDF-SHA-256. Since this
dependency is in the code, declare it there rather than with the data.
If the depenency is not met, mark the test as skipped since it can't
create the key to be tested.

These implementations don't necessarily consume entropy the same way the
mbed TLS internal software implementation does, and the 'reference
handshake' test vectors can thus not be applied to an ALT implementation.

While builtin keys will often have a fixed-size context, this is not
necessarily the case, so the "get_builtin_key" entry point needs to
return the size of the actual key context.

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.

There were explicit dependencies on header files for some test suites,
dating back from when only a few test suites depended on anything in
tests/include. The noted dependencies were still correct, but now that
tests/include is more populated, they were only the tip of the
iceberg. Just keep it simple and depend on all the headers.

`tests/scripts/all.sh check_python_files` now runs mypy (in addition
to pylint) if it's available. So install mypy.
Install mypy 0.780, which is the earliest version that works on our
code at this time.
