For TLS 1.3 tests, do not force TLS 1.3
version on client to play the negotiation
game whenever possible.

To maximize the number of tests where MbedTLS
client proposes both TLS 1.2 and TLS 1.3 to
the server, force the TLS 1.2 version on the
server side rather than on the client side
in TLS 1.2 specific tests.

This implies that when both TLS 1.2 and TLS 1.3
are included in the build all the TLS 1.2 tests
using the default configuration now go through
a version negotiation on the client side.

In TLS 1.3 key sharing is not restricted to key
exchange with certificate authentication. It
happens in the PSK and ephemeral key exchange
mode as well where there is no certificate
authentication.

Add some MBEDTLS_SSL_PROTO_TLS1_3 guards that will
be necessary when the ClientHello writing code is
made available when MBEDTLS_SSL_PROTO_TLS1_2 is
enabled.

This can only be TLS 1.2 now in this structure and when
adding support for TLS 1.2 or 1.3 version negotiation
the highest configured version can be TLS 1.3.

The TLS server code only support TLS 1.2 thus simplify
the check of the version proposed by the client.

ssl_tls12_client.c contains only TLS 1.2 specific
code thus remove some checks on the minor version
version being MBEDTLS_SSL_MINOR_VERSION_3. No aim
for completeness, ssl_parse_server_hello() is not
reworked here for example.

In ssl_tls.c, move mbedtls_ssl_set_calc_verify_md() under the
"if defined(MBEDTLS_SSL_PROTO_TLS1_2)" pre-processor directive
as it is specific to TLS 1.2.

ssl_set_handshake_prfs() is TLS 1.2 specific and only called
from TLS 1.2 only code thus no need to pass the TLS minor
version of the currebt session.

In TLS 1.3, a PSA ECDH private key may be created
even if MBEDTLS_SSL_USA_PSA_CRYPTO is disabled. We
must destroy this key if still referenced by an
handshake context when we free such context.

In case of TLS 1.3 and hybrid TLS 1.2/1.3, propose
PKCS1 v1.5 signatures with SHA_384/512 not only
SHA_256. There is no point in not proposing them
if they are available.
In TLS 1.3 those could be useful for certificate
signature verification.
In hybrid TLS 1.2/1.3 this allows to propose for
TLS 1.2 the same set of signature algorithms.

This has although the benefit of getting rid of a
potential integer overflow (though very unlikely
and probably harmless).

Rename ssl_cli.c and ssl_srv.c to reflect the fact
that they are TLS 1.2 specific now. Align there new
names with the TLS 1.3 ones.
