[heap] Reset global limit on global context disposal

Global context disposal (no dependent contexts) resets the regular JS
heap limit and marks the old generation as not configured. This is
used for embedders to signal that all contexts went away and a new
workload is started.

Also reset the global heap limit in this disposal as the JS and C++
heaps are intertwined.

Sheriffs: This may move GC scheduling a lot as it likely delays the
first GC in benchmarks. It's possible to see average memory
consumption go up and GC time decrease. Steady-state memory should be
unaffected though.

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 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/*
