The new compile-time option MBEDTLS_X509_REMOVE_INFO removes various
X.509 debugging strings and functionality, including
```
mbedtls_x509_crt_verify_info()
```
which ssl_client2.c and ssl_server2.c use to print human readable
descriptions of X.509 verification failure conditions. Those
conditions are also grepped for in numerous ssl-opt.sh tests.
Instead of disabling those tests if MBEDTLS_X509_REMOVE_INFO is set,
this commit essentially moves mbedtls_x509_crt_verify_info() to
ssl_client2.c and ssl_server2.c. However, instead of just copy-pasting
the code from x509_crt.c, the following approach is used:
A macro MBEDTLS_X509_CRT_ERROR_INFO_LIST is introduced which for each
verification failure condition invokes a user-defined macro X509_CRT_ERROR_INFO
with (a) the numerical error code, (b) the string presentation of the
corresponding error macro, (c) the info string for the error condition.
This macro can thus be used to generate code which somehow iterates over
the verifiation failure conditions, but the list of error conditions and
information strings is nowhere duplicated.
This is then used to re-implement mbedtls_x509_crt_verify_info() in
x509_crt.c and to provide a functionally equivalent (yet slightly different)
version in ssl_client2.c and ssl_server2.c in case MBEDTLS_X509_REMOVE_INFO
is set.
This way, little changes to ssl-opt.sh will be necessary in case
MBEDTLS_X509_REMOVE_INFO is set because the info strings for the
verification failure conditions will be printed regardless of whether
MBEDTLS_X509_REMOVE_INFO is set or not.

The introduction of positive options to control the presence
of pre-existing functionality breaks the build for users of
handwritten configurations.

Introduce MBEDTLS_X509_INFO to indicate the availability of the
mbedtls_x509_*_info() function and closely related APIs. When this is
not defined, also omit name and description from
mbedtls_oid_descriptor_t, and omit OID arrays, macros, and types that
are entirely unused. This saves several KB of code space.

Add implementation for MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS
Merging as it has been ready for four days now and I prefer not having to go through other rebases especially given the coming change of scope of development (3.0 rather than 2.2x).
If the compile-time configuration enables an option that was removed
in Mbed TLS 3.0, and the effect of removing the option would likely
not be detected at build time, #error out in check_config.h.

Specifically allow the driver to override the persistency level of a
builtin key in cases where the driver is persistency-aware.
