[3.7] bpo-24334: Cleanup SSLSocket (GH-5252) (#5857) 

* The SSLSocket is no longer implemented on top of SSLObject to
  avoid an extra level of indirection.
* Owner and session are now handled in the internal constructor.
* _ssl._SSLSocket now uses the same method names as SSLSocket and
  SSLObject.
* Channel binding type check is now handled in C code. Channel binding
  is always available.

The patch also changes the signature of SSLObject.__init__(). In my
opinion it's fine. A SSLObject is not a user-constructable object.
SSLContext.wrap_bio() is the only valid factory.
(cherry picked from commit 141c5e8c24)

Internal implementation details of ssl module were cleaned up. The SSLSocket
has one less layer of indirection. Owner and session information are now
handled by the SSLSocket and SSLObject constructor. Channel binding
