It requires adding if after every SSL_CONNECTION_FROM_SSL() call

It can be useful to know what group was used for the handshake's
key exchange process even on non-TLS 1.3 connections. Allow this
API, new in OpenSSL 3.0.0, to be used on other TLS versions as well.
Since pre-TLS-1.3 key exchange occurs only on full handshakes, this
necessitates adding a field to the SSL_SESSION object to carry the
group information across resumptions. The key exchange group in the
SSL_SESSION can also be relevant in TLS 1.3 when the resumption handshake
uses the "psk_ke" key-exchange mode, so also track whether a fresh key
exchange was done for TLS 1.3.
Since the new field is optional in the ASN.1 sense, there is no need
to increment SSL_SESSION_ASN1_VERSION (which incurs strong incompatibility
churn).

This removes man unnecessary OPENSSL_NO_DH guards from libssl. Now that
libssl is entirely using the EVP APIs and implementations can be plugged
in via providers it is no longer needed to disable DH at compile time in
libssl. Instead it should detect at runtime whether DH is available from
the loaded providers.

We had a couple of stray references to OpenSSL1.2 in libssl. We just
reword the comments to remove those references without changing any
behaviour.
The first one in t1_lib.c is a technical non-compliance in the TLSv1.3
spec where, under some circumstances, we offer DSA sigalgs even in a
ClientHello that eventually negotiates TLSv1.3. We explicitly chose to
accept this behaviour in 1.1.1 and we're not planning to change it for
3.0.
The second one in s3_lib.c is regarnding the behaviour of
SSL_set_tlsext_host_name(). Technically you shouldn't be able to call
this from a server - but we allow it and just ignore it rather than
raising an error. The TODO suggest we consider raising an error instead.
However, with 3.0 we are trying to minimise breaking changes so I suggest
not making this change now.

We fix 3 problems with safestack:
- Including an openssl header file without linking against libcrypto
can cause compilation failures (even if the app does not otherwise need
to link against libcrypto). See issue #8102
- Recent changes means that applications in no-deprecated builds will need
to include additional macro calls in the source code for all stacks that
they need to use - which is an API break. This changes avoids that
necessity.
- It is not possible to write code using stacks that works in both a
no-deprecated and a normal build of OpenSSL. See issue #12707.
