RSA-OAEP requires the key to be larger than a function of the hash size.
Ideally such combinations would be detected as a key/algorithm
incompatibility. However key/algorithm compatibility is currently tested
between the key type and the algorithm without considering the key size, and
this is inconvenient to change. So as a workaround, dispense
OAEP-with-too-small-hash from exercising, without including it in the
automatic operation-failure test generation.

Don't try to use {sign,verify}_message on algorithms that only support
{sign_verify}_hash. Normally exercise_key() tries all usage that is
supported by policy, however PSA_KEY_USAGE_{SIGN,VERIFY}_MESSAGE is implied
by PSA_KEY_USAGE_{SIGN,VERIFY}_HASH so it's impossible for the test data to
omit the _MESSAGE policies with hash-only algorithms.

Don't re-code the logic to determine a valid nonce length.
This fixes exercise_key() for PSA_ALG_CHACHA20_POLY1305, which was trying to
use a 16-byte nonce.

Support ECB, which has no IV. The code also now supports arbitrary IV
lengths based on the algorithm and key type.

In key read tests, add usage flags that are suitable for the key type and
algorithm. This way, the call to exercise_key() in the test not only checks
that exporting the key is possible, but also that operations on the key are
possible.
This triggers a number of failures in edge cases where the generator
generates combinations that are not valid, which will be fixed in subsequent
commits.

When generating storage format tests, pass usage flags around as a list, and
format them as the last thing.
In Storagekey(), simplify the addition of implicit usage flags: this no
longer requires parsing.
The output is unchanged.

In the generated storage format test cases, cover all supported
algorithms for each key type. This is a step towards exercising
the key with all the algorithms it supports; a subsequent commit
will generate a policy that permits the specified algorithms.

- comments about (3)DES were inconsistent (one saying "keep 3DES" and
the other "exclude it")
- we don't have any DES or 3DES ciphersuite anyway, so no need to
exclude them or comment about it

The ciphers were originally separated by the version conditions, and the spacing
was retained in case it was required later. It has been decided it would be better
to have an unbroken list in alphabetically order to quickly locate ciphers when
necessary

When running check-generated-files in update mode, all generated files were
regenerated. As a consequence,
```
tests/scripts/check-generated-files.sh -u && make
```
always caused most of the code to be rebuilt. Now, if a file hasn't changed,
preserve its original modification time (and other metadata), so the command
above doesn't rebuild anything that has actually not changed.

Otherwise the error status can be PSA_ERROR_INVALID_SIGNATURE instead of the
expected PSA_ERROR_NOT_SUPPORTED in some configurations. For example, the
RSA verification code currently checks the signature size first whenever
PSA_KEY_TYPE_RSA_PUBLIC_KEY is enabled, and only gets into
algorithm-specific code if this passes, so it returns INVALID_SIGNATURE even
if the specific algorithm is not supported.
