			This commit upstreams most of the C++ bits of the LibJS test262 runner at https://github.com/linusg/libjs-test262/, specifically everything but the main.cpp file serving as the actual executable. Since all of these are just regular JS objects, I opted to put them in LibJS itself, in a new Contrib/ directory like many other projects have one. Other code that can end up there in the future is the runtime for esvu, which might even share some functionality with test262's $262 object. The code has been copied verbatim, and only a small number of changes have been made: - Putting everything into the JS::Test262 namespace - Removing now redundant JS namespace prefixes - Updating includes to use absolute <LibJS/...> paths - Updating the SPDX-License-Identifier comments from MIT to BSD-2-Clause I gained permission to change the license and upstream these changes from all the major contributors to this code: Ali, Andrew, David, Idan. The removal of the code from the source repository is here: https://github.com/linusg/libjs-test262/pull/54 This is only the first step, the goal is to eventually upstream the actual libjs-test262-runner executable and supporting Python scripts into SerenityOS as well.
