Remove support for Token Binding

This removes most Token Binding code from chromium. There are a few
places that still have Token Binding references (but will go unused)
that can possibly be removed in the future. These are:
- android_webview/
- net/third_party/quic/
- third_party/tlslite/

There are two UMA histograms in //net that also have TokenBinding in
their name; these are (confusingly) used by Channel ID code as part of
the work on debugging Channel ID mismatches, and can be removed with the
rest of the Channel ID code.
