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.

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.

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.
