Chris Tate 079a9d1eb5 Add tlsSocket.getProtocol, getCipher, alpnProtocol and tls.DEFAULT_MIN_VERSION/MAX_VERSION

- getProtocol() answers the negotiated version ("TLSv1.2" or
  "TLSv1.3"), the highest version on offer before the handshake as
  OpenSSL does, and null after close.
- getCipher() answers { name, standardName, version }: OpenSSL's name
  for the negotiated suite, its IANA name, and the suite's minimum
  protocol version. A suite without a known OpenSSL name throws the
  "not supported yet" error.
- alpnProtocol is null before the handshake, then the negotiated
  protocol or false.
- tls.DEFAULT_MIN_VERSION and DEFAULT_MAX_VERSION are 'TLSv1.2' and
  'TLSv1.3', and the bundled declarations type the server's
  secureConnection socket as a TLSSocket.
- The limitations page notes that a typed getCipher() read before the
  handshake or after close throws where Node answers undefined or null.
Corpus 5651 covers each case.
