cppgc: Hello world

"By my deeds I honor him. V8."

- Add basic build files for library and unittests.
- Integrate unittests also in existing V8 unittests for simplicity.

The CL also adds FinalizerTrait and unittests to allow building a
testing target that executes code.

FinalizerTrait is used to determine how managed C++ types are
finalized. The trait should not be overridable by users but needs to
be exposed on API-level to avoid including library-internal headers.

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/*
