            blink: Implement V8's crash key interface

            This CL implements the new crash key API used in V8 to report
            crash keys on OOM errors. The API basically only forwards to
            Chrome's internal crash key API.

            As a cleanup this CL also moves this setup to v8_initializer.cc,
            where most callbacks are set up.
