[DevTools] Switch inspector-test.cc to use the CBOR encoded inspector state.

The main change here is that in isolate-data.h, I'm switching from stateJSON to state.
This routine returns a CBOR encoded state cookie, which is also what we already
use in Chromium (blink).

In inspector-test.cc, I then put this byte vector into a V8 String,
and to make this roundtrip, change the extraction routine to get the
bytes. It's a little weird to store arbitrary bytes inside a v8 string,
but it appears to work fine because these bytes end up in the 8 bit portion,
much like isolatin characters would.

V8 JavaScript Engine

V8 is Google's open source JavaScript engine.

V8 implements ECMAScript as specified in ECMA-262.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 can run standalone, or can be embedded into any C++ application.

V8 Project page: https://v8.dev/docs

Getting the Code

Checkout depot tools, and run

    fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*


Please follow the instructions mentioned at v8.dev/docs/contribute.
