New Revision: 8b7ea912e516a6daa61487c700687a9426e3a396

Update v8 files / build config accordingly.
- There's now a new library in third_party/inspector_protocol,
  bindings/bindings.h, which is configured much like encoding/encoding.h.
  It doesn't have much stuff in it yet, but will soon get more code
  that would otherwise need to go into jinja templates.
  It also comes with a new test, only a smoke test thus far.
