Tamer Tas 26ce64e5ee [v8][layout-tests] create src-side definitions for {chromium_integration} bots
We have Blink layout test bots on 3 different platforms using the
{blink_downstream} recipe. {chromium_integration} uses src-side definitions for
compilation and blink tests.

This CL creates the src-side bot definitions for Chromium integration with Blink
Layout tests.

MB - The Meta-Build wrapper

MB is a simple wrapper around the GN build tool.

It was originally written as part of the GYP->GN migration, in order to provide a uniform interface to either GYP or GN, such that users and bots can call one script and not need to worry about whether a given bot was meant to use GN or GYP.

It eventually grew additional functionality and is now still used even though everything is GN-only.

It supports two main functions:

  1. "gen" - the main gn gen invocation that generates the Ninja files needed for the build.

  2. "analyze" - the step that takes a list of modified files and a list of desired targets and reports which targets will need to be rebuilt.

We also use MB as a forcing function to collect all of the different build configurations that we actually support for Chromium builds into one place, in //tools/mb/mb_config.pyl.
