Check for TLS 1.3 version first when parsing
the supported versions extension as it is
the most likely version.

Set hybrid TLS 1.2/1.3 as default server
configuration if both TLS 1.2 and TLS 1.3
are enabled at build time.

Postpone TLS 1.3 cipher suite selection
when we are sure we negotiate the version
1.3 of the protocol.

To avoid doing it twice in case we eventually
negotiate the version 1.2 of the protocol,
postpone the copy of the legacy session id.

When parsing the ClientHello message,
move the setting of the TLS version
to TLS 1.3 after the computation of
the end of the list of cipher suites.
At that point we are able to compute
the address and end address of the
list of extensions and thus able to
search and parse the supported_versions
extension to select which version
of the TLS protocol we are going to
negotiate.

Move in a dedicated function the search for the
supported_versions extension in a list of
extensions, to be able to use it on server side
as well.

Force TLS 1.2 on TLS 1.2 specific tests in
preparation of TLS 1.3 being the default
protocol version when both TLS 1.2 and
TLS 1.3 are enabled.

Force TLS 1.2 version on tests related to
MBEDTLS_SSL_ASYNC_PRIVATE, CA callback and
MBEDTLS_SSL_MAX_FRAGMENT_LENGTH. Those
SSL options are not supported in TLS 1.3
for the time being. Thus force TLS 1.2
version in preparation of TLS 1.3 being
the default protocol version when both
TLS 1.2 and TLS 1.3 are enabled.

Remove unnecessary explicit MBEDTLS_SSL_PROTO_TLS1_2
dependency if TLS 1.2 version is forced or a TLS 1.2
cipher suite is forced (as TLS 1.2 cipher suites are
available if and only if TLS 1.2 is enabled and
cipher suite availability is check automatically).

Move min/max TLS version setting to endpoint init
where it fits better: before the call to
mbedtls_ssl_setup() and available for all tests
not only those calling perform_handshake().

Instead of using the legacy mbedtls_ecp_check_pub_priv() function which
was based on ECP math, we add a new option named eckey_check_pair_psa()
which takes advantage of PSA.
Of course, this is available when MBEDTLS_USE_PSA_CRYPTO in enabled.
Tests were also fixed accordingly.
