Free up space in the session cache before adding.

Fixes #18690

In some circumstances, it's possible that when using an external
database for the session cache, that pulling in an entry from that
cache to the internal cache will cause the newly added entry to
be deleted from the internal cache. This is likely to happen when
the internal cache is set to have a small size, and the newly added
entry's timeout places it at the end of the cache list.

This could be fixed by updating the timestamp of the session (via
`SSL_SESSION_set_time()` or `SSL_SESSION_set_timeout()`) before
adding to the cache. But that may not be desireable.

SSL object refactoring using SSL_CONNECTION object

Make the SSL object polymorphic based on whether this is
a traditional SSL connection, QUIC connection, or later
to be implemented a QUIC stream.

It requires adding if after every SSL_CONNECTION_FROM_SSL() call
which itself has to be added to almost every public SSL_ API call.

Concentrate deprecated libssl API usage in one file

We create a new file ssl/tls_depr.c to contain functions that need to call
deprecated APIs in libssl. This enables us to remove
OPENSSL_SUPPRESS_DEPRECATED from a number of other libssl files.

The deprecated API usage is either related to ENGINEs and is needed to
continue to support applications that use such ENGINEs. Or they are needed
to support some deprecated public libssl APIs.

One other file remains in libssl that still uses deprecated APIs: s3_cbc.c
This is needed to support the deprecated SSLv3.

The previous 2 commits moved supported groups and ciphers out of the
session object to avoid race conditions. We now also move ecpointformats
for consistency. There does not seem to be a race condition with access
to this data since it is only ever set in a non-resumption handshake.
However, there is no reason for it to be in the session.

Fix a race condition in ciphers handling

Similarly to the previous commit we were storing the peer offered list
of ciphers in the session. In practice there is no need for this
information to be avilable from one resumption to the next since this
list is specific to a particular handshake. Since the session object is
supposed to be immutable we should not be updating it once we have decided
to resume. The solution is to remove the session list out of the session
object.

Fix a race condition in supported groups handling

In TLSv1.3 the supported groups can be negotiated each time a handshake
occurs, regardless of whether we are resuming or not. We should not store
the supported groups information in the session because session objects
can be shared between multiple threads and we can end up with race
conditions. For most users this won't be seen because, by default, we
use stateless tickets in TLSv1.3 which don't get shared. However if you
use SSL_OP_NO_TICKET (to get stateful tickets in TLSv1.3) then this can
happen.

The answer is to move the supported the supported group information into
the SSL object instead.
