Mostly to reflect this has been implemented, and remove references to
temporary remains from the previous strategy (hash_info, legacy_or_psa)
which would probably be more confusing than helpful at this point.

We shouldn't violate the requirement that the key identifier can be
reused. In practice, a key manager may destroy a key that's in use by
another process, and the privileged world containing the key manager and
the crypto service should not be perturbed by an unprivileged process.
With respect to blocking, again, a key manager should not be blocked
indefinitely by an unprivileged application.
These are desirable properties even in the short term.

The Docker container used for the CI has Git version 2.7.4 which
does not support the "git branch --show-current" command since this
was added in version 2.22.
Therefore this commit adds an alternative version for old Git versions.

The support for the PSA crypto driver interface
is not optional anymore as the implementation of
the PSA cryptography interface has been restructured
around the PSA crypto driver interface (see
psa-crypto-implementation-structure.md). There is
thus no purpose for the configuration options
MBEDTLS_PSA_CRYPTO_DRIVERS anymore.

md-cipher-dispatch.md

- Support for PSA_CRYPTO_CLIENT without PSA_CRYPTO_C is out of scope for
now but might be added later (the architecture supports that).
- While we're using a void pointer for md_ctx, we don't need a union
here; the union will be useful only if & when we remove the indirection.

Now that the script only makes before-after comparison, it no longer
makes sense to ignore some test suites.

It's a rare scenario, but it's currently possible: if you use
mbedtls_cipher_xxx() to encrypt the communication between the application
and the crypto service, changing those functions to call PSA will break your
system.

Finish working out the RSA-PSS example in terms of what it implies about the
interface. The key takeaway is that a mixed-domain module must support
algorithms if they are available through either interface, and that's all
there is to it. The details of how dispatch is done don't matter, what
matters is only the availability, and it's just the disjunction of
availabilities.

Add TLS 1.3 specific configuration options
to enable/disable the support for TLS 1.3
key exchange modes.
These configurations are introduced to
move away from the aforementioned
enablement/disablement based on
MBEDTLS_KEY_EXCHANGE_xxx_ENABLED options
that relate to group of TLS 1.2
ciphersuites.

Instead of having a list of test suites of interest, have a list of
suites to ignore and look at all the others.
In order for this to only yield interesting results, we need to tune the
reference configuration a bit, in order to exclude STREAM and ECB to
more closely match the driver-based configuration.

Currently just replacing existing uses, but the real point of having

Strategy for dependencies inside libmbecrypto, in particular in the PSA
Crypto core, are outside the scope of the present study.
Note: PR 6065, referenced in a few places, is the one that also
introduces the present commit. It kicks of the work towards G5 in parts
of the code governed by MBEDTLS_USE_PSA_CRYPTO.

- lack of support for PSA_CRYPTO_CONFIG is not really a reason not to
enable MBEDTLS_USE_PSA_CRYPTO by default - while it's true that
currently X.509/TLS do not behave as expected when PSA_CRYPTO_CONFIG and
MBEDTLS_USE_PSA_CRYPTO are both enabled, it's no worse than when
MBEDTLS_USE_PSA_CRYPTO is disabled.
- as a consequence of removing the paragraph mentioned above, the
sub-section about PSA_CRYPTO_CONFIG no longer belongs in the
"compile-time option" section. Also, it's superseded by the study work
that happened in the meantime (of which this PR is part). So let's
remove it, and the new commit will add something more up-to-date
instead.

Not related to the changes in this PR, except in the next commit I'll

things that needed updated, so here there are in their own commit.
