wolfSSL: fix session management bug.

Prior to this commit, non-persistent pointers were being used to store
sessions. When a WOLFSSL object was then freed, that freed the session
it owned, and thus invalidated the pointer held in curl's cache. This
commit makes it so we get a persistent (deep copied) session pointer
that we then add to the cache. Accordingly, wolfssl_session_free, which
was previously a no-op, now needs to actually call SSL_SESSION_free.

This bug was discovered by a wolfSSL customer.

This is how the RFC calls the protocol. Also rename the file in docs/ to

content_encoding: use writer struct subclasses for different encodings

The variable-sized encoding-specific storage of a struct contenc_writer
currently relies on void * alignment that may be insufficient with
regards to the specific storage fields, although having not caused any
problems yet.

In addition, gcc 11.3 issues a warning on access to fields of partially
allocated structures that can occur when the specific storage size is 0:

content_encoding.c: In function ‘Curl_build_unencoding_stack’:
content_encoding.c:980:21: warning: array subscript ‘struct contenc_writer[0]’ is partly outside array bounds of ‘unsigned char[16]’ [-Warray-bounds]
980 | writer->handler = handler;
| ~~~~~~~~~~~~~~~~^~~~~~~~~
In file included from content_encoding.c:49:
memdebug.h:115:29: note: referencing an object of size 16 allocated by ‘curl_dbg_calloc’
115 | #define calloc(nbelem,size) curl_dbg_calloc(nbelem, size, __LINE__, __FILE__)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
content_encoding.c:977:60: note: in expansion of macro ‘calloc’
977 | struct contenc_writer *writer = (struct contenc_writer *)calloc(1, sz);

To solve both these problems, the current commit replaces the
contenc_writer/params structure pairs by "subclasses" of struct
contenc_writer. These are structures that contain a contenc_writer at
offset 0. Proper field alignment is therefore handled by the compiler and
full structure allocation is performed, silencing the warnings.
