Add new mbedtls_pkcs12_pbe_ext function to replace
old mbedtls_pkcs12_pbe function that have security
issues.

In make builds, when GEN_FILES is false (empty), don't try to re-generate
configuration-independent source files, regardless of whether they seem
out of date. This is useful, for example, if you have a source tree where
`make generated_files` has already run and file timestamps reflect the
time the files were copied or extracted, and you are now in an environment
that lacks some of the necessary tools to re-generate the files.

In case of an out-of-tree build with the CMake build
system the path to crypto_config.h has to be defined
as the path to mbedtls_config.h. Add this possibility
tp generate_query_config.pl.

Fix defined but not used warning when
MBEDTLS_USE_PSA_CRYPTO, MBEDTLS_PK_HAVE_RFC8410_CURVES
and MBEDTLS_PK_HAVE_ECC_KEYS are defined but not
MBEDTLS_PEM_WRITE_C.

This is not required (it's ok to define the default in mbedtls_config and
skip the definition in rsa.h), but comment it out for uniformity with all
the other options in this section.

Fix unused variable when MBEDTLS_SSL_PROTO_TLS1_3 and
MBEDTLS_SSL_SESSION_TICKETS are enabled but not MBEDTLS_DEBUG_C.

Mbed TLS can be configured by writing a configuration file from scratch,
without copying mbedtls_config.h. As a consequence, all the macro
definitions in mbedtls_config.h must be optional. This was not the case for
some MBEDTLS_SSL_TLS1_3_xxx macros with numerical values related to session
tickets. Fix that.

Boolean options that modify the behavior of a module are supposed to be in
the "feature support" section, not in the "configuration options" support:
that section is documented to contain commented-out definitions with a
value, for which the comment contains the default version. In particular,
merely uncommenting a definition in the "configuration options" section is
not supposed to change anything.
Move the offending boolean options to the proper section.
This causes those options to be enabled by `config.py full` unless
explicitly excluded. For all the offending options, this is undesirable, so
make sure those options are indeed excluded.

* Prevent pkcs12_pbe encryption when PKCS7 padding has been
disabled since this not part of the specs.
* Allow decryption when PKCS7 padding is disabled for legacy
reasons, However, invalid padding is not checked.
* Document new behaviour, known limitations and possible
security concerns.
* Add tests to check these scenarios. Test data has been
generated by the below code using OpenSSL as a reference:
#include <openssl/pkcs12.h>
#include <openssl/evp.h>
#include <openssl/des.h>
#include <openssl/asn1.h>
#include "crypto/asn1.h"
#include <string.h>
