Subject: openssl: remove attached easy handles from SSL instances

 - keeping the "current" easy handle registered at SSL* is no longer
   necessary, since the "calling" data object is already stored in the
   cfilter's context (and used by other SSL backends from there).
 - The "detach" of an easy handle that goes out of scope is then avoided.
 - using SSL_set0_wbio for clear reference counting where available.

Closes #10151
