[api] Add v8::ScriptCompiler::CachedData::CompatibilityCheck()

This patch adds a new API v8::ScriptCompiler::CachedData::CompatibilityCheck()
in order to allow embedders to check if the code cache can be used in
the current isolate without looking up for the source code. It also returns more detailed reasons about why the code cache cannot be used
when it's bound to be rejected. This makes it possible to enforce
portability checks in case code code becomes CPU-dependent in the
future.

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/*
