With multipart AEAD, if we attempt to add zero length additional data,
then with the buffer sharing fixes this can now lead to undefined
behaviour when using gcm. Fix this by returning early, as there is
nothing to do if the input length is zero.

Like `openssl rsa`, `openssl genrsa` changed its output format from PKCS8 to
PKCS1 in OpenSSL 3.0. Note that the makefile instructions assume older
OpenSSL. Convert the files that were generated with OpenSSL 3.x and hence
were not in the intended format. The files are converted, not regenerated,
so the key material is the same.

With OpenSSL 3.0.2 (which I used to generate the previous set of "pkcs1" DER
files), the output of `openssl rsa -outform DER` is actually a
PKCS#8-encoded key, despite what the documentation says. This is a change
from OpenSSL 1.x, where the output is a PKCS#1-encoded key. OpenSSL 3.0.8
documents the output as PKCS#8.
Change to `openssl pkey`, which seems more reliable. The documentation
states that the output is PKCS#8, but the output is actually consistently
PKCS#1 at least from 1.0.2g to 3.3.0.

When PSA is available, we exercise the parsed RSA key with PKCS#1v1.5
signature, which requires the modulus size in bytes to be at least
tLen + 11 (per RFC 8017 §9.2) where tLen = hLen + oidLen + 6 and
hLen = 32, oidLen = 9 for SHA-512 or SHA3-512. 10 is the DER overhead
(3 ASN.1 type-length headers with lengths <128). Replace 512-bit test
cases (good enough for SHA-256 but not SHA-384 and up) by 768-bit and
up (good enough for SHA-512).

These are sufficiently large for PKCS#1v1.5 signature with SHA-512 or
SHA3-512. Cover some non-word-aligned sizes.

The previous commit had:
- one obvious mistake (-f NULL with default -e runs nothing)
- one unforeseen issue: OPENSSL_NEXT skips static ECDH
- arguably scope creep: the stated goal was to simplify the full
invocation (in particular, make it obvious that everything is run
without having to remember the default value of EXCLUDE), but it also
made an unrelated change: running most tests with OPENSSL_NEXT (hence
the previous point).
This commit should fix all this, in particular it switches back to
running most tests with OPENSSL and using OPENSSL_NEXT only when needed.
Hopefully in the future we'll do the opposite: most tests will run with
a recent OpenSSL, and only those that need an older one will use
something older. But that will be another PR.

RSA needs ASN1 functions to parse/write private and public keys,
but there is no guards in the code for that. So we need to enable
ASN1 support whenever RSA is enabled.

We actually only need two invocations.
This also moves all the default tests to OPENSSL_NEXT, which is good
because OPENSSL is ancient.
I have no idea why NULL doesn't work with OPENSSL_NEXT (1.1.1a) server,
because according to the manpage [1], "ALL,COMPLEMENTOFALL" (which is
what we are using) should do it, and indeed
$OPENSSL_NEXT ciphers "ALL,COMPLEMENTOFALL" | tr ':' '\n'
lists NULL ciphersuites, and also they work client-side with
OPENSSL_NEXT...

Also, while at it, remove partial invocation (only non-default) from one
component, as we already have a full invocation in the same config (plus
ASan) in another component.

- MBEDTLS_GENPRIME is removed because now we rely on predefined
RSA keys.
- MBEDTLS_RSA_GEN_KEY_MIN_BITS is replaced with RSA_KEY_SIZE which
is set on top of test_suite_pk to a value which is supported
in the predefined_keys[] array.

This is to manage RSA and EC keys in the same way in order to
prepare for the following commits.

asymmetric_key_data.py already provides EC/RSA key pair values that
are suitable for generate_test_keys.py. So instead of re-generating
the keys using gen_key program, we use those keys.
This commit also:
- extends asymmetric_key_data.py to introduce
RSA bit sizes that are used in test_suite_pk but were missing from
asymmetric_key_data.py.
- updates test_keys.h with new keys.

- remove BEGIN_FILE/END_FILE lines from output header file.
- add single disclaimer at the beginning of the file instead
of having it repeated for every array.
- improved exception message for missing key generation program.
This commits also regenerates "test_keys.h" in order to fully
comply with the new format.

This commit adds "generate_test_keys.py" script to generate
predefined keys used in test_suite_pk. Keys are generated with
"programs/pkey/gen_key" tool and converted to C array using
the python script.
tests/src/test_keys.h is automatically generated using the
above mentioned script.
test_suite_pk is updated in order to use the new format.

Instead of using PK module to import/export the key in a PSA friendly
format:
- for RSA keys we use the DER input data directly;
- for EC keys we extract the private key manually.
This helps avoiding dependencies from PK_WRITE and PK_PARSE.
